Summary: Predicted to enable serine-type endopeptidase inhibitor activity. Acts upstream of or within response to cytokine and response to peptide hormone. Located in collagen-containing extracellular matrix. Is expressed in axial skeleton; liver; nervous system; and thymus primordium. Human ortholog(s) of this gene implicated in chronic obstructive pulmonary disease; cystic fibrosis; and vasculitis. Orthologous to human SERPINA3 (serpin family A member 3).

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.
