Summary: Enables serine-type endopeptidase inhibitor activity. Acts upstream of or within several processes, including in utero embryonic development; protein N-linked glycosylation; and response to peptide hormone. Located in extracellular region. Is expressed in gut; liver lobe; nucleus pulposus; and renal calyx. Human ortholog(s) of this gene implicated in several diseases, including alpha 1-antitrypsin deficiency; artery disease (multiple); chronic obstructive pulmonary disease (multiple); inflammatory bowel disease (multiple); and liver disease (multiple). Orthologous to human SERPINA1 (serpin family A member 1). [provided by Alliance of Genome Resources, Nov 2024]
Expression: Biased expression in liver adult (RPKM 6265.9), liver E18 (RPKM 2144.9) and 2 other tissues See more

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.
