Serpinb1a - serine (or cysteine) peptidase inhibitor, clade B, member 1a

Predicted to enable peptidase inhibitor activity. Predicted to contribute to serine-type endopeptidase inhibitor activity. Involved in several processes, including negative regulation of interleukin-1 beta production; regulation of innate immune response; and type B pancreatic cell proliferation. Acts upstream of or within regulation of protein catabolic process. Located in extracellular region. Is expressed in bladder wall; brain; embryo mesenchyme; gut; and liver lobe. Orthologous to human SERPINB1 (serpin family B member 1). [provided by Alliance of Genome Resources, Apr 2022]
