UniProtKB - Q00896 (A1AT3_MOUSE)
Protein
Alpha-1-antitrypsin 1-3
Gene
Serpina1c
Organism
Mus musculus (Mouse)
Status
Functioni
Inhibitor of serine proteases. Can inhibit trypsin and chymotrypsin; relatively ineffective against elastase.2 Publications
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.

Domaini
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.By similarity
Sequence similaritiesi
Belongs to the serpin family.Curated
