Human Serpin I2 (SerpinI2) Protein

Background

SERPINI2 is a member of the serine protease inhibitor (serpin) family and is encoded by the SERPINI2 gene located on chromosome 3. The serpin superfamily comprises a large group of proteins that inhibit proteolytic enzymes, playing crucial roles in various biological processes such as blood coagulation, fibrinolysis, immune response, and tissue remodeling. Like other serpins, SERPINI2 regulates the activity of proteases by acting as a suicide substrate, forming a stable complex with the target protease, which leads to its irreversible inhibition. Although SERPINI2 is not as well-studied as other members of the serpin family, recent studies suggest that it is involved in the regulation of proteolysis in various tissues, with significant expression observed in pancreatic, hepatic, and other glandular tissues.
