Serpin B6 (serine protease inhibitor-clade B#6; also placental thrombin inhibitor) is a 42 kDa, cytosolic member of the ovalbumin (clade B)-subfamily, Serpin superfamily of protease inhibitors. It is produced by multiple cell types (keratinocytes; monocytes; mast cells), and shows inhibitory activity towards thrombin, plasmin and chymotrypsin. Human Serpin B6 is 376 amino acids (aa) in length. An active inhibitor site lies between Glu327 and Met338. Multiple potential isoforms exist. One shows a 28 aa substitution for the N-terminal 191 amino acids. Three others have alternate start sites that vary from 14‑33 aa’s upstream of the standard start site. Human Serpin B6 shares 76% aa identity with mouse Serpin B6.
