Summary: Predicted to enable serine-type endopeptidase inhibitor activity. Involved in several processes, including inflammatory response; negative regulation of interleukin-1 beta production; 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, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
