Introduction
A human infecting coronavirus (viral pneumonia) called 2019 novel coronavirus, 2019-nCoV was found in the fish market at the city of Wuhan, Hubei province of China on December 2019.
The 2019-nCoV shares an 87% identity to the 2 bat-derived severe acute respiratory syndrome 2018 SARS-CoV-2 located in Zhoushan of eastern China. 2019-nCoV has an analogous receptor-BD-structure to that of 2018 SARS-CoV, even though there is a.a. diversity so thus the 2019-nCoV might bind to ACE2 receptor protein (angiotensin-converting enzyme 2) in humans.
While bats are possibly the host of 2019-nCoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the 2019-nCoV is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.

Introduction
EPCAM is a carcinoma-associated antigen and belongs to a family which includes at least 2 type I membrane proteins. The EPCAM protein has a role in embryonic stem cells proliferation and differentiation. EPCAM is used as a target for immunotherapy treatment of human carcinomas. EPCAM is expressed on most normal epithelial cells and gastrointestinal carcinomas and acts as a homotypic calcium-independent cell adhesion molecule. Epithelial cell adhesion molecules (EPCAM) can act as a physical homophilic interaction molecule between intestinal epithelial cells (IECs) and intraepithelial lymphocytes (IELs) at the mucosal epithelium for supplying immunological barrier as a first line of defense against mucosal infection. EPCAM gene mutations result in congenital tufting enteropathy.

Introduction
The 26S proteasome is a multicatalytic proteinase complex with a well ordered structure composed of two complexes- a 20S core and a 19S regulator. PSMD11 is a non-ATPase subunit of the 19S regulator. The 20S core is composed of four rings of 28 non-identical subunits; two rings are composed of 7 alpha subunits and two rings are composed of 7 beta subunits. The 19S regulator is composed of a base that contains six ATPase subunits and two non-ATPase subunits, and a lid that contains up to ten non-ATPase subunits. Proteasomes are spread throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An indispensable function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides.

Introduction
C1QBP having the accession number of NP_001203 binds to the globular "heads" of c1q thus inhibiting c1 activation. C1QBP interacts with a wide range of ligands and is implicated in cell signaling. C1QBP associates with C1r and C1s in order to yield the first component of the serum complement system. C1QBP protein has been identified as the p32 subunit of pre-mRNA splicing factor SF2, as well as a hyaluronic acid-binding protein.
C1QBP is a new marker of tumor cells and tumor-associated macrophages/myeloid cells in hypoxic/metabolically deprived areas of tumors.
Mitochondrial C1QBP is a critical mediator of p14ARF-induced apoptosis.
C1QBP functions as a chemotactic factor for immature dendritic cells, and migration is mediated through ligation of both C1QBP and cC1qR/CR.
C1QBP overexpression successfully blocks mRNA accumulation from the adenovirus major late transcription unit (MLTU) and stimulates RNA polymerase II carboxy-terminal domain phosphorylation in virus-infected cells.
C1QBP binds with Hepacivirus core protein on CD8+ and CD4+ positive t-cells and inactivates lck and akt. -

Introduction
Gliadin is a common substrate of transglutaminase, which generates neo-epitopes by deamidation of glutamine side chains. In the past, serologic tests for gliadin antibodies usually were not very precise and were not enough for accurate diagnosis due to missing deamidated epitopes within the authentic gliadin fraction traditionally used in diagnostic test kits. ProSpec's deamidated Gliadin isoform matches to the deamidated neo-epitopes, which in the natural antigen are formed by transglutaminase-mediated glutamine side chain deamidation.

Background
Severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) have caused significant outbreaks with severe respiratory illness in recent years. The spike proteins of these viruses play a crucial role in viral entry and host cell recognition. This research aims to explore the structure, function, and implications of SARS and MERS spike proteins in viral pathogenesis and the development of therapeutic interventions. Understanding the mechanisms of viral entry can provide valuable insights into the design of effective antiviral strategies.
Structure and Function of SARS and MERS Spike Proteins:
The spike proteins of SARS-CoV and MERS-CoV are trimeric glycoproteins located on the viral surface. They consist of S1 and S2 subunits, with the S1 subunit responsible for receptor binding and the S2 subunit involved in membrane fusion. The spike proteins contain key domains, including the receptor-binding domain (RBD) and the fusion peptide, which mediate the interactions with host cell receptors and membrane fusion during viral entry.
Interaction with Host Cell Receptors:
The SARS-CoV spike protein primarily interacts with the angiotensin-converting enzyme 2 (ACE2) receptor, which is expressed in various tissues, including the respiratory tract. The binding of the SARS-CoV spike protein to ACE2 is crucial for viral entry into host cells. Similarly, the MERS-CoV spike protein interacts with the dipeptidyl peptidase 4 (DPP4) receptor, which is predominantly expressed in the lungs and other tissues. These receptor interactions determine the host range and tissue tropism of the viruses.
Implications for Viral Pathogenesis:
The interaction between the spike proteins of SARS-CoV and MERS-CoV and their respective receptors initiates a cascade of events leading to viral entry and replication. The binding of the spike protein to the receptor triggers conformational changes that expose the fusion peptide, facilitating membrane fusion and viral entry into host cells. The specificity and affinity of the spike-receptor interaction play a critical role in determining viral tropism, disease severity, and transmission dynamics.
Therapeutic Strategies Targeting Spike Proteins:
The spike proteins of SARS-CoV and MERS-CoV present attractive targets for the development of antiviral interventions. Various approaches have been explored, including the development of neutralizing antibodies that specifically target the spike proteins and inhibit viral entry. Additionally, small molecule inhibitors and peptide-based therapeutics are being investigated to disrupt the spike-receptor interaction and block viral entry. Vaccine development efforts have also focused on generating immune responses against the spike proteins to prevent infection.
Challenges and Future Directions:
Although significant progress has been made in understanding the structure and function of SARS and MERS spike proteins, several challenges remain. The emergence of novel coronavirus variants necessitates continuous surveillance and adaptation of therapeutic strategies. Additionally, potential cross-reactivity and immunogenicity concerns need to be addressed to ensure the safety and efficacy of spike protein-based therapeutics.
Conclusion:
The study of SARS and MERS spike proteins provides valuable insights into the mechanisms of viral entry and pathogenesis. Understanding the interactions between spike proteins and host cell receptors is crucial for the development of effective antiviral strategies. Further research on spike protein structure, receptor binding, and fusion mechanisms is essential to combat current and future coronavirus outbreaks. By unraveling the complexities of viral entry, we can pave the way for the development of novel therapeutics to mitigate the impact of SARS-CoV, MERS-CoV, and related coronaviruses.

Introduction
HCV is a small 50nm, enveloped, single-stranded, positive sense RNAvirus in the family Flaviviridae.
HCV has a high rate of replication with approximately one trillion particles produced each day in an infected individual. Due to lack of proofreading by the HCV RNA polymerase, the HCV has an exceptionally high mutation rate, a factor that may help it elude the host's immune response. Hepatitis C virus is classified into six genotypes(1-6) with several subtypes within each genotype. The preponderance and distribution of HCV genotypes varies globally. Genotype is clinically important in determining potential response to interferon-based therapy and the required duration of such therapy. Genotypes 1 and 4 are less responsive to interferon-based treatment than are the other genotypes (2, 3, 5 and 6). -
Stability
HCV NS5B although stable at 4°C for 1 week, should be stored below -18°C. Please prevent freeze thaw cycles.

Introduction
West Nile virus (WNV) is a virus of the family Flaviviridae part of the Japanese encephalitis (JE) antigenic complex of viruses. Image reconstructions and cryoelectron microscopyreveal a 45-50 nm virion covered with a relatively smooth proteinsurface. This structure is similar to virus; both belong to the genus flavivirus within the family Flaviviridae. WNV is a positive-sense, single strand of RNA, it is between 11,000 and 12,000 nucleotides long which encode seven non-structural proteins and three structural proteins. The RNA strand is held within a nucleocapsid formed from 12 kDaprotein blocks; the capsid is contained within a host-derived membrane altered by two viral glycoproteins.
-
Stability
WNV Pre-M although stable at 4°C for 1 week, should be stored below -18°C. Please prevent freeze thaw cycles.

Introduction
Glycogen phosphorylase is one of the phosphorylaseenzymes(EC2.4.1.1). It breaks up glycogeninto glucosesubunits. Glycogenis left with one less glucosemolecule, and the free glucosemolecule is in the form of glucose-1-phosphate. In order to be used for metabolism, it must be converted to glucose-6-phosphateby the enzyme phosphoglucomutase.
Glycogen phosphorylase can only act on linearchainsof glycogen(a 1-4 glycosidic linkage). Its work will immediately come to a halt four residues away from a 1-6 branch(which are exceedingly common in glycogen). In these situations, a debranching enzymeis necessary, which will straighten out the chain in that area. Additionally, an alpha 1-6 glucosidaseenzymeis required to break the remaining 1-6 residue that remains in the new linear chain. After all this is done, glycogen phosphorylase can continue.
An insulinstimulated enzyme known as phosphoprotein phosphatase(PP-1) inactivates glycogen phosphorylase to prevent glycogen break up.
GPBB - a sensitive marker for the AMI diagnosis within 4 hours after the onset of chest pain. It has also been shown that GPBB is increased in a considerable proportion of AMI patients within 2-3 hours from chest pain onset. GPBB is increased early in patients with unstable angina. GPBB can also be a sensitive marker for the detection of peri-operative myocardial ischaemia and infarction in patients undergoing coronary artery bypass grafting. -

Introduction
A human infecting coronavirus (viral pneumonia) called 2019 novel coronavirus, 2019-nCoV was found in the fish market at the city of Wuhan, Hubei province of China on December 2019.
The 2019-nCoV shares an 87% identity to the 2 bat-derived severe acute respiratory syndrome 2018 SARS-CoV-2 located in Zhoushan of eastern China. 2019-nCoV has an analogous receptor-BD-structure to that of 2018 SARS-CoV, even though there is a.a. diversity so thus the 2019-nCoV might bind to ACE2 receptor protein (angiotensin-converting enzyme 2) in humans.
While bats are possibly the host of 2019-nCoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the 2019-nCoV is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.

Introduction
C1QBP binds to the globular "heads" of c1q thus inhibiting c1 activation. C1QBP interacts with a wide range of ligands and is implicated in cell signaling. C1QBP associates with C1r and C1s in order to yield the first component of the serum complement system. C1QBP protein has been identified as the p32 subunit of pre-mRNA splicing factor SF2, as well as a hyaluronic acid-binding protein.
C1QBP is a new marker of tumor cells and tumor-associated macrophages/myeloid cells in hypoxic/metabolically deprived areas of tumors.
Mitochondrial C1QBP is a critical mediator of p14ARF-induced apoptosis.
C1QBP functions as a chemotactic factor for immature dendritic cells, and migration is mediated through ligation of both C1QBP and cC1qR/CR.
C1QBP overexpression successfully blocks mRNA accumulation from the adenovirus major late transcription unit (MLTU) and stimulates RNA polymerase II carboxy-terminal domain phosphorylation in virus-infected cells.
C1QBP binds with Hepacivirus core protein on CD8+ and CD4+ positive t-cells and inactivates lck and akt. -

Introduction
NCK2 belongs to the NCK family of adaptor proteins. NCK2 holds one SH2 domain and three SH3 domains. NCK2 bind and recruit several proteins that take part in the regulation of receptor protein tyrosine kinases even though it has no known catalytic function. That indicates that NCK2 takes part in cytoskeletal reorganization. Alternate transcription splice variants, encoding diverse isoforms, were characterized.

Introduction
NEFL or Neurofilament light polypeptide is a protein that is encoded through the NEFL gene. NEFL is correlated to a disease called Charcot–Marie–Tooth. The protein’s light subunit is determined by immunoassays in the plasma and cerebrospinal fluid, if present, it can indicate on axonal damage in neurological diseases. By doing so, NEFL can act as a marker for Huntington's disease, Amyotrophic Lateral Sclerosis and multiple sclerosis.

Introduction
Neurexophilin 1 (NXPH1) is a part of the neurexophilin family which encodes a secreted protein with a variable N terminal domain, an extremely conserved, N-glycosylated central domain, a short linker region, and a cysteine-rich Cterminal domain. NXPH1 shapes a very tight complex with alpha neurexins, a group of proteins which promote adhesion among dendrites and axons.
