General annotation (Comments)Hide

Function	Inhibitor of serine proteases. Its primary target is elastase, but it also has a moderate affinity for plasmin and thrombin. Ref.6 Ref.7
Subcellular location	Secreted Ref.6 Ref.7.
Domain	The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable By similarity. Variability within the reactive center loop (RCL) sequences of Serpina1-related genes may determine target protease specificity.
Miscellaneous	Murine alpha-1-antitrypsin is represented by a cluster of up to 6 individual Serpina1-related genes. The precise complement of Serpina1-related genes present varies according to the strain of the animal.
Sequence similarities	Belongs to the serpin family.
