Serpinb3a - serine (or cysteine) peptidase inhibitor, clade B (ovalbumin), member 3A

Predicted to enable endopeptidase inhibitor activity; protease binding activity; and virus receptor activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to be located in cytoplasmic vesicle; extracellular exosome; and nucleus. Predicted to be active in extracellular space. Orthologous to human SERPINB3 (serpin family B member 3) and SERPINB4 (serpin family B member 4). [provided by Alliance of Genome Resources, Apr 2022]
