Summary: Enables cysteine-type endopeptidase inhibitor activity and serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Predicted to be located in several cellular components, including cytoplasmic vesicle; cytosol; and extracellular exosome. Predicted to be active in extracellular space. Is expressed in genital tubercle and gonad. Orthologous to human SERPINB3 (serpin family B member 3) and SERPINB4 (serpin family B member 4). [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.
