Background: Peptidase Inhibitor 16/PI16

PI16 (Peptidase Inhibitor 16) is a variable molecular weight (MW) member of the CRISP family of proteins. It is expressed by cardiomyocytes and serves as an autocrine negative growth regulator. Mature mouse PI16 is a type I transmembrane protein 469 amino acids (aa) in length. The extracellular region includes all but the C‑terminal 21 amino acids. A soluble form of PI16 is known. Although its predicted MW is 50 kDa, it runs anomalously at 70 kDa (unmodified) in SDS-PAGE. With glycosylation, it appears to be 100‑110 kDa in size. Three potential variants exist. One shows a deletion of aa 51‑124, a second shows a 9 aa extension at the N‑terminus, and a third shows a deletion of aa 191‑452. Over aa 1‑464, mouse PI16 shares 86% and 61% aa identity with rat and human PI16, respectively.
