Gene ID: 5272 | Gene type: protein coding

About SERPINB9

Cytogenetic location: 6p25.2 Genomic coordinates (GRCh38): 6:2,887,270-2,903,309 (from NCBI)

This gene has 1 transcript (splice variant), 150 orthologues and 36 paralogues. Broad expression in placenta (RPKM 26.1), appendix (RPKM 19.1) and 21 other tissues.

Summary

This gene encodes a member of the Serine Protease Inhibitor family which are also known as serpins. The encoded protein belongs to a subfamily of intracellular serpins. This protein inhibits the activity of the effector molecule granzyme B. Overexpression of this protein may prevent cytotoxic T-lymphocytes from eliminating certain tumor cells. A pseudogene of this gene is found on chromosome 6. [provided by RefSeq, Mar 2012]
