Biological Activity
Vaspin (visceral adipose-specific SERPIN) is also a unique insulin sensitizing adipocytokine in obesity. A recent publication indicates th at induction of human vaspin mRNA expression in adipose tissue is regulated in a f at 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.
