Introduction
GST family of enzymes comprises a long list of cytosolic, mitochondrial, and microsomal proteins that are 45-55 kDa (dimer form) size and are capable of multiple reactions with a multitude of substrates, both endogenous and xenobiotic. GST catalyses the conjugation of reduced glutathione meaning the sulfhydryl group, to electrophilic centers on a wide variety of substrates. This activity is useful in the detoxification of endogenous compounds such as peroxidised lipids, as well as the metabolism of xenobiotics. GST binds toxins and function as transport protein. Glutathione S-transferase is used to create the so-called ''GST gene fusion system''. The GST is used to purify and detect proteins of interest. In a GST gene fusion system, the GST sequence is incorporated into an expression vector alongside the gene sequence encoding the protein of interest. Induction of protein expression from the vector''s multiple cloning sites results in expression of a fusion protein - the protein of int

Introduction
Liraglutide is a long-acting GLP1 analogue sharing 97% a.a. homology to human GLP1. Liraglutide differs from GLP1 by the substitution of arginine for lysine at position 34. While GLP1 is degraded swiftly by DPP4 resulting in short life of insulin, Liraglutide contains a fatty acid that binds to albumin and prolongs the half-life of the structure. liraglutide causes insulin to secret in the presence of increasing glucose levels. Due toits receptor site, liraglutide inhibits glucagon secretion and delays gastric emptying.

Introduction
NTRK1 plays a role in the development and survival of nerve cells (neurons), specifically those that transmit dataregarding senses such as touch, pain and temperatureie. sensory neurons. NTRK1 protein is located on surface cells, mainly such as sensory neurons. NTRK1 acts as a kinase enzyme that alters the activity of different proteins by adding anoxygen cluster and phosphorus atoms at precise positions ie. phosphorylation. NTRK1 activated by nerve growth factor beta which binds to it and signals the NTRK1 protein to phosphorylate itself. Post autophosphorylation, the activated NTRK1 protein phosphorylates other proteins which is required for cell growth and survival.

Introduction
IL-17 family members are glycoproteins secreted as dimers which induce local cytokine production and recruit granulocytes to sites of inflammation. The IL-17 family is comprised of at least six pro-inflammatory cytokines that share a conserved cysteine-knot structure but diverge at the N-terminus. IL-17 is induced by IL-15 and IL-23, mostly in activated CD4+ T cells distinct from Th1 or Th2 cells. IL-17B binds the IL-17B receptor, but not the IL-17 receptor; it is most homologous with IL-17D, which is expressed by resting CD4+ T cells and CD19+ B cells. IL17B Diseases associated with IL17B include spondyloarthropathy, and neuronitis, and among its related super-pathways are Mucin expression in CF via IL-6, IL-17 signaling pathways and STAT3 Pathway.

Introduction
Twisted gastrulation Protein (TSG) is a secreted, cysteine-rich protein which has a role in dorsal/ventral patterning in Drosophila and Xenopus by regulating BMP signaling. TSG functions as an agonist for BMP signaling by controlling the inhibitory actions of the BMP antagonist, Chordin/Sog, and the cleavage properties of the metalloprotease, xolloid/tolloid. TSG N-terminal domain binds BMP protein directly and displays BMP antagonist activity.

Introduction
Leptin is a protein hormone. It is mainly produced in adipose cells that regulate energy homeostasis by restraining hunger. Leptin ties to nuclear receptors in the hypothalamus (arcuate nucleus). Similar to insulin resistance in type II diabetes, in obesity there is a decrease in the sensitivity towards leptin, ending in a failure to identify satiety, even in high levels of energy stores or leptin itself. Full-length cDNA encoding 2 leptin sequences (tLepA and tLepB) and 1 leptin receptor sequence (tLepR) exists in tilapia (Oreochromis niloticus). The full-length cDNA of tLepR is 3423 bp, encoding a protein of 1140 amino acid which contained all functionally important domains conserved among vertebrate leptin receptors. The cDNAs of tLepA and tLepB are 486 bp and 459 bp in length, encoding proteins of 161 aa and 152 aa, respectively.

Introduction
Terlipressin is similar to a naturally occurring hormone present in the body, known as antidiuretic hormone (ADH) or vasopressin. ADH has two main effects in the body. Firstly, it causes narrowing of blood vessels (vasoconstriction), thereby limiting blood flow to a particular area of the body. It also acts on receptors in the kidney to retain water in the body, which helps to prevent excessive loss of water in the urine. Terlipressin is commonly used to stop bleeding of varices in the food pipe (oesophagus). Varices are fragile distended veins that can occur in various parts of the body such as the oesophagus. This is caused by an increase in blood pressure in certain diseases such as severe liver disease. These fragile varices can rupture and lead to life threatening bleeding. Terlipressin is therefore given to narrow blood vessels, and so restricting blood flow to the varices and stopping the bleeding.

Background
Vasoactive Intestinal Peptide (VIP), a prominent member of the glucagon-secretin peptide superfamily, plays a multifaceted role as a neuropeptide and neurotransmitter. This research paper aims to provide an extensive analysis of VIP, exploring its biochemical properties, diverse physiological functions, and potential therapeutic applications in various disease conditions.
Vasoactive Intestinal Peptide (VIP), originally identified for its potent vasodilatory properties in the gastrointestinal system, has since been recognized for its wide-ranging physiological effects throughout the body. As a neuropeptide and neurotransmitter.
VIP, a 28-amino acid peptide, exhibits a diverse range of biological activities due to its interactions with multiple G protein-coupled receptors (GPCRs) from the VIP/PACAP receptor family (Harmar et al., 2012). These receptors are expressed in various tissues and cells, enabling VIP to exert its pleiotropic effects.
VIP is involved in the regulation of numerous physiological processes. It functions as a potent vasodilator, modulates smooth muscle activity in the gastrointestinal tract, and participates in neurotransmission in the central and peripheral nervous systems (Lelievre et al., 2008). Additionally, VIP has immunomodulatory properties, influencing immune cell functions and inflammatory responses (Delgado et al., 2004).
VIP serves as a neurotransmitter in the central nervous system, where it contributes to various neuronal functions, including learning, memory, and sensory perception (Deng et al., 2015). Moreover, VIP has demonstrated neuroprotective effects in neurodegenerative disorders, making it a potential therapeutic target for neuroprotection and neuroregeneration (Delgado et al., 2002).
VIP's diverse physiological functions offer potential therapeutic applications in various disease contexts. Research has explored its potential in the treatment of inflammatory diseases, neurodegenerative disorders, and gastrointestinal disorders (Delgado et al., 2013). Furthermore, VIP-based therapies are being investigated for their neuroprotective potential in brain injuries and stroke.
As the research on VIP continues to progress, further investigation is warranted to uncover the precise mechanisms of action and potential clinical applications in medicine. VIP stands as a remarkable example of a neuropeptide with extensive physiological roles and therapeutic potential in various disease conditions.

Introduction
Wheat Gliadin and related gluten components from barley, rye and possibly oats can cause an abnormal immune response called Celiac disease which is a chronic gastrointestinal disorder. Celiac disease characteristics are flattening of the jejunal mucosa and intestinal lesions of variable severity in hereditarily inclined individuals. Even though Celiac disease is not a classic autoimmune disease it is related to anti-tissue transglutaminase antibodies and gliadin antibodies tests are most recommended in screening populations at risk for CD and other gluten-sensitive enteropathies. 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.

Introduction
Chikungunya is an infection caused by the chikungunya virus which is passed to humans by two species of mosquito of the genus Aedes: A. albopictus and A. aegypti. Animal reservoirs of the virus include monkeys, birds, cattle, and rodents. The features of the disease are a sudden onset of fever 2-4 days after exposure. The fever typically lasts 2-7 days, while the associated joint pains usually last weeks or months but sometimes years. The mortality rate is a little less than 1 in 1,000. The disease has occurred in outbreaks in Asia, Europe and the Americas since 2004. CHIKV is a single-stranded positive-sense RNA genome, 11,800 nts long which encodes 2 open reading frames. The nucleocapsid is tightly enveloped by a host-derived lipid bilayer (envelope) supporting the virus-encoded envelope proteins. 80 glycoprotein spikes are C- terminally anchored within the viral envelope. The structural polyprotein is translated from a viral sub genomic mRNA, while as the 5 structural proteins (capsid, E3, E2, 6K, E1) are translated as a single polyprotein, from which capsid (C) is cleaved off to encapsidate. The envelope polyprotein precursor E3-E2-6K-E1 is translocated to the endoplasmatic reticulum. Polyprotein is processed by host signalases, resulting in E3, E2 & E1 forming viral hetero-trimeric spikes. The viral spikes majorly contains E2 and E1 facilitate cell receptor recognition, cell entry thru pH-dependent endocytosis and support viral budding.

Introduction
Cell division protein kinase 5 (CDK5) belongs to the cyclin-dependent kinase family. CDK5 is essential for appropriate development of the brain and in order to be activated CDK5 must link to CDK5R1 or CDK5R2. CDK5 doesn't need phosphorylation on the T loop so that binding with the activator is enough to activate the kinase. CDK5 is engaged in the processes of neuronal maturation and migration, phosphorylating the central intracellular adaptor of the reeling signaling chain.

Introduction
Mitogen-activated protein kinase 1 (MAPK1) is also known as "extracellular signal-regulated kinase 2" (ERK2). Two similar (85% sequence identity) protein kinases were originally called ERK1 and ERK2. They were found during a search for protein kinases that are rapidly phosphorylated after activation of cell surface tyrosine kinasessuch as the epidermal growth factor receptor. Phosphorylation of ERKs leads to the activation of their kinase activity.
The molecular events linking cell surface receptors to activation of ERKs are complex. It was found that RasGTP-binding proteins are involved in the activation of ERKs. Another protein kinase, Raf-1, was shown to phosphorylate a "MAPK kinase", thus qualifying as a "MAPK kinase kinase". The MAPK kinase was named "MAPK/ERK kinase" (MEK).
Receptor-linked tyrosine kinases, Ras, Raf, MEK and MAPK could be fitted into a signaling cascade linking an extracellular signal to MAPK activation.
Transgenic gene knockoutmice lacking MAPK1 have major defects in early development. -

Description
The class IA PI3Kd is expressed in endothelial and in white blood cells. Recently it was shown that the inactivation of PI3Kd in bone marrow mast cells (BBMCs) leads to defective stem cell factor-mediated proliferation, adhesion and migration of these cells, and to impaired allergen-IgE induced degranulation and cytokine release. In neutrophils a role for PI3Kd in TNFa-induced signaling was demonstrated by a reduction in Aktphosphorylation and PDK1 activity upon treatment with the d-specific inhibitor IC87114. The catalytic subunit carries a GST-Tag which facilitates the protein’s application in typical GST pull-down assays and the heterodimer was purified by affinity chromatography. The molecular weight for p110d chain is 120.2 kDa (without Tag) and the p85a chain 83.5 kDa.

Introduction
Glutaminyl-Peptide Cyclotransferase, also known as QPCT is a member of the glutaminyl-peptide cyclotransferase family. QPCT is responsible for the biosynthesis of pyroglutamyl peptides. Furthermore, QPCT is partial against acidic and tryptophan residues adjacent to the N-terminal glutaminyl residue and a lack of importance of chain length following the second residue. QPCT catalyzes N-terminal pyroglutamate formation, also in vitro, it catalyzes pyroglutamate formation of N-terminally truncated form of APP amyloid-beta peptides [Glu-3]-beta-amyloid.
