Summary: Enables serine-type endopeptidase inhibitor activity. Acts upstream of or within peptide hormone processing; response to cold; and response to dietary excess. Located in extracellular space; secretory granule; and trans-Golgi network. Is expressed in several structures, including alimentary system; early conceptus; genitourinary system; nervous system; and sensory organ. Orthologous to human PCSK1N (proprotein convertase subtilisin/kexin type 1 inhibitor). [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.
