Summaries for SERPINB9 Gene

Entrez Gene Summary for SERPINB9 Gene

  • 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]

GeneCards Summary for SERPINB9 Gene

SERPINB9 (Serpin Peptidase Inhibitor, Clade B (Ovalbumin), Member 9) is a Protein Coding gene. Among its related pathways are Amoebiasis. GO annotations related to this gene include serine-type endopeptidase inhibitor activity and cysteine-type endopeptidase inhibitor activity involved in apoptotic process. An important paralog of this gene is SERPINB12.
