products description :
Alpha1-Antichymotrypsin (AACT) is a serine proteinase inhibitor and minor acute phase protein with a molecular weight of ~68kD, occurring in serum at 250-500mg/L. AACT appears to inhibit chymotrypsin specifically.

ncbi 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]
uniprot summary :
SERPINA1: Inhibitor of serine proteases. Its primary target is elastase, but it also has a moderate affinity for plasmin and thrombin. Irreversibly inhibits trypsin, chymotrypsin and plasminogen activator. The aberrant form inhibits insulin-induced NO synthesis in platelets, decreases coagulation time and has proteolytic activity against insulin and plasmin. Defects in SERPINA1 are the cause of alpha-1-antitrypsin deficiency (A1ATD). A disorder whose most common manifestation is emphysema, which becomes evident by the third to fourth decade. A less common manifestation of the deficiency is liver disease, which occurs in children and adults, and may result in cirrhosis and liver failure. Environmental factors, particularly cigarette smoking, greatly increase the risk of emphysema at an earlier age. Belongs to the serpin family. 3 isoforms of the human protein are produced by alternative splicing. Protein type: Inhibitor; Secreted; Secreted, signal peptide. Chromosomal Location of Human Ortholog: 14q32.1. Cellular Component: Golgi apparatus; proteinaceous extracellular matrix; extracellular space; endoplasmic reticulum; extracellular region. Molecular Function: serine-type endopeptidase inhibitor activity; identical protein binding; protein binding; protease binding; glycoprotein binding. Biological Process: platelet activation; response to chromate; platelet degranulation; response to triglyceride; response to cytokine stimulus; response to lead ion; response to methanol; acute-phase response; response to hypoxia; response to lipopolysaccharide; blood coagulation; response to estradiol stimulus. Disease: Alpha-1-antitrypsin Deficiency; Pulmonary Disease, Chronic Obstructive
