SERPINB4 serpin family B member 4 [Homo sapiens (human)] - Gene

Summary

Official Symbol: SERPINB4provided by HGNC
Official Full Name: serpin family B member 4provided by HGNC
Primary source: HGNC:HGNC:10570
See related: Ensembl:ENSG00000206073 MIM:600518; AllianceGenome:HGNC:10570
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: PI11; SCCA1; SCCA2; LEUPIN; SCCA-2
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.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
