11019

Antigen Name:

Serpin Peptidase Inhibitor, Clade A, Member 1

CPTC Name:

CPTC-SERPINA1

Aliases:

AAT; PI; PI1; alpha1AT1; alpha-1-antitrypsin1; A1AT; A1A; Serpin A1; Alpha-1 protease inhibitor; serine (or cysteine) proteinase inhibitor, clade A (alpha-1 antiproteinase,
antitrypsin), member 1; OTTHUMP00000197154; MGC23330; OTTHUMP00000197150; PRO2275; MGC9222; protease inhibitor 1 (anti-elastase), alpha-1-antitrypsin; alpha-1-antiproteinase

Function:

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.

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.

Short peptide from AAT (SPAAT) is a reversible chymotrypsin inhibitor. It also inhibits elastase, but not
trypsin. Its major physiological function is the protection of the lower respiratory tract against proteolytic
destruction by human leukocyte elastase (HLE).
