Background: Serpin A12

Serpin A12 (serine proteinase inhibitor-clade A#12; also known as vaspin) is a 45‑50 kDa secreted member of the alpha 1-antitrypsin (clade A)-subfamily, Serpin superfamily of protease inhibitors. It is produced by visceral adipocytes, and adipocyte-derived stem cells during obesity or diabetes. The presence of vaspin reverses insulin-resistance. Its molecular target is unknown. Human Serpin A12 is 414 amino acids (aa) in length. It contains a 20 aa signal sequence and a 394 aa mature region. A potential "active" inhibitor site lies between Arg363 and Met378. Mature human Serpin A12 shares 61% aa identity with mouse Serpin A12.
