Serpin A9 (Serine proteinase inhibitor-clade A #9; also GCET1, Centerin and Serpin A11) is a 46 kD, secreted member of the a1-antitrypsin (clade A)-subfamily, serpin superfamily of protease inhibitors. It is only produced by normal and lymphoma germinal center B cells. Its function is unknown, but it presumably acts as an inhibitor of a trypsin-like protease. Mature human Serpin A9 is presumably 394aa in length. It contains one Serpin motif (aa405-415). There are multiple splice variants associated with Serpin A9. There are alternate start sites at Met19, Met99 and Met150. A fourth isoform shows a two aa substitution for (aa369-435), while a fifth isoform shares this same substitution coupled with a 39aa substitution for (aa1-75). A sixth variant shows a deletion of (aa91-190). Mature human Serpin A9 shares 67% aa identity with mouse Serpin A9.
