General description
Vaspin (visceral adipose-specific SERPIN), a newly identified adipokine, is a member of serine protease inhibitor family. It is also known as serpin family A member 12 (SERPINA12). The gene encoding this protein is localized on human chromosome 14q32.13. Recombinant human Vaspin produced in E. coli is a single, non-glycosylated polypeptide chain containing 415 amino acids and having a molecular mass of 47kDa.
Biochem/physiol Actions
Vaspin (visceral adipose-specific SERPIN) is also a unique insulin sensitizing adipocytokine in obesity. A recent publication indicates that induction of human vaspin mRNA expression in adipose tissue is regulated in a fat depot-specific manner and could be associated with parameters of obesity, insulin resistance, and glucose metabolism. This protein may be useful as a biomarker with patients with acute myocardial infarction. It is a ligand of the 78kDa glucose-regulated protein/murine transmembrane protein (GRP78/MTJ-1) complex and has indirect effects on endoplasmic reticulum stress-induced metabolic disorders.
