About ERP / Endoplasmic Reticulum Protein:
The endoplasmic reticulum protein is the involved transmission and transportation grounding of the eukaryotic cell. It is an organelle comprised of the rough endoplasmic reticulum and smooth endoplasmic reticulum. The former is found in cells such as hepatocytes, while the latter is commonly found in the liver and gonad cells.
It has many purposes, with its most notable being that of protein folding.
ERP Structure
The endoplasmic reticulum is structured via a thin membrane network named cisternae, formed and held by the cytoskeleton therein. The function of this involves a synthesis between the exporting of proteins and membrane lipids, depending on cell type and function. According to the metabolic processes of the cell, the amount of rough and smooth endoplasmic reticulum can shift each way in kind.
Endoplasmic Reticulum Protein Mechanism
The endoplasmic reticulum membrane has secretory proteins (in large part glycoproteins) moved across it. These proteins are marked with an ‘address tag’ known as a signal sequence. When the polypeptide reaches its endpoint, the amino acids that work as this tag are removed. As such, the ER serves as a transportation system of the eukaryotic cell, serving as a protein sorting pathway.
ERP Function
When redox regulation isn’t functioning as normal, a lack of glucose, a viral infection, or overexpression of necessary proteins can lead to an endoplasmic reticulum stress response. An abnormality in XBP1 can also lead to a heightened ERS stress response, and this can contribute to an increased chance for an inflammatory response, potentially causing a higher likelihood for diseases like Alzheimer’s and Crohn’s disease.
