NCIt definition : Serpin B3 (390 aa, 45 kDa) is encoded by the human SERPINB3 gene. This protein is
involved in the inhibition of serine- and cysteine-type proteinases.;
NCIt note : Serpin B3 can be proteolytically processed into smaller fragments that aggregate to
form an autoantigen in psoriasis. (EntrezGene);
