other info1 :
Source Note: Human serum/plasma. Protein Type: Native. Biological Significance: Alpha 1-antichymotrypsin is an alpha globulin glycoprotein that is a member of the serpin superfamily. It inhibits the activity of certain enzymes called proteases, such as cathepsin G that is found in neutrophils, and chymases found in mast cells, by cleaving them into a different shape or conformation. This activity protects some tissues, such as the lower respiratory tract, from damage caused by proteolytic enzymes.

ncbi summary :
The protein encoded by this gene is a plasma protease inhibitor and member of the serine protease inhibitor class. Polymorphisms in this protein appear to be tissue specific and influence protease targeting. Variations in this protein's sequence have been implicated in Alzheimer's disease, and deficiency of this protein has been associated with liver disease. Mutations have been identified in patients with Parkinson disease and chronic obstructive pulmonary disease. [provided by RefSeq, Jul 2008]
uniprot summary :
SERPINA3: Although its physiological function is unclear, it can inhibit neutrophil cathepsin G and mast cell chymase, both of which can convert angiotensin-1 to the active angiotensin-2. Belongs to the serpin family. 3 isoforms of the human protein are produced by alternative splicing. Protein type: Secreted, signal peptide; Secreted. Chromosomal Location of Human Ortholog: 14q32.1. Cellular Component: extracellular space; extracellular region; intracellular; nucleus. Molecular Function: serine-type endopeptidase inhibitor activity; protein binding; DNA binding. Biological Process: regulation of lipid metabolic process; maintenance of gastrointestinal epithelium; acute-phase response; inflammatory response
