Background

Serpin B8 (serine proteinase inhibitor‑clade B #8; also PI8) is a 42‑45 kDa, cytoplasmic and secreted member of the ovalbumin (clade B)‑subfamily, Serpin superfamily of protease inhibitors. It is produced by multiple cell types and shows inhibitory activity towards furin and other proteinases such as chymotrypsin. Human Serpin B8 is 374 amino acids (aa) in length. Although it has no signal sequence, it is released by platelets. The active inhibitor site lies between Arg336 and Arg342. One potential isoform shows a 2 aa substitution for the C‑terminal 134 amino acids. Full length human Serpin B8 shares 78% and 83% aa identity with mouse and canine Serpin B8, respectively.
