SERPINB4 - serpin family B member 4 Gene
Also Known as PI11; SCCA1; SCCA2; LEUPIN; SCCA-2
Species: Homo sapiens
About SERPINB4
This gene has 4 transcripts (splice variants), 222 orthologues and 36 paralogues. Biased expression in esophagus (RPKM 63.1), urinary bladder (RPKM 11.6) and 1 other tissue.
Summary
The protein encoded by this gene is a member of the Serpin family of serine Protease Inhibitors. The encoded protein is highly expressed in many tumor cells and can inactivate granzyme M, an enzyme that kills tumor cells. This protein, along with Serpin B3, can be processed into smaller fragments that aggregate to form an autoantigen in psoriasis, probably by causing chronic inflammation.
