NCIt definition : Serpin B4 (390 aa, 45 kDa) is encoded by the human SERPINB4 gene. This protein plays
a role in the inhibition of protease activity for enzymes such as granzyme M.;
NCIt note : Serpin B4 can be proteolytically processed into smaller fragments that aggregate to
form an autoantigen in psoriasis. (EntrezGene);
