GENE AND PROTEIN SUMMARY

? »

Gene name

SERPINA1

Description

serpin peptidase inhibitor, clade A (alpha-1 antiproteinase, antitrypsin), member 1

Protein class

Candidate cancer biomarkers, Candidate cardiovascular disease genes, Mapped to UniProt SWISS-PROT, Plasma proteins, Potential transmembrane proteins, Potentially secreted proteins

Protein evidence

High

Entrez gene summary

The protein encoded by this gene is secreted and is a serine protease inhibitor whose targets include elastase, plasmin, thrombin, trypsin, chymotrypsin, and plasminogen activator. Defects in this gene can cause emphysema or liver disease. Several transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]
