Human Serpin A11 Antibody

Serpin A11 (serine proteinase inhibitor – clade A#11) is a 50-60 kDa secreted member of the serpin superfamily of protease inhibitors.  Serpins are the largest family of endogenous protease inhibitors, and target a wide variety of serine and cysteine proteases.  In general, members of this superfamily regulate multiple proteolytic cascades, and are particularly effective due to the fact that their inhibitory activities can be fine-tuned through the participation of discrete, non-serpin co-factors.  Serpin A11 gene expression is extremely high in normal liver, with lower levels detected in normal breast, breast tumor, and benign prostatic hyperplasia.  Human Serpin A11 is 422 amino acids (aa) in length, with four potential N-linked glycosylation sites, and shares 75% aa sequence identity with mouse Serpin A11.
