Gene: SERPINA1 (serpin family A member 1) Homo sapiens
Symbol: SERPINA1
Name: serpin family A member 1
Description: Exhibits identical protein binding activity; protease binding activity; and serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Localizes to Golgi apparatus; endoplasmic reticulum; and extracellular space. Implicated in several diseases, including alpha 1-antitrypsin deficiency; chronic obstructive pulmonary disease (multiple); human immunodeficiency virus infectious disease; inflammatory bowel disease (multiple); and liver disease (multiple). Biomarker of acute pancreatitis; artery disease (multiple); colorectal cancer; osteoarthritis; and pancreatic cancer (multiple).
Type: protein-coding
RefSeq Status: REVIEWED
