Summary: Predicted to enable several functions, including enzyme binding activity; phosphatidylcholine binding activity; and retinoic acid binding activity. Involved in spermatogenesis. Predicted to be located in several cellular components, including external side of plasma membrane; extracellular exosome; and secretory granule. Predicted to be part of several cellular components, including protein C inhibitor-KLK3 complex; protein C inhibitor-PLAT complex; and protein C inhibitor-PLAU complex. Predicted to be active in extracellular space. Is expressed in several structures, including epithelium; genitourinary system; gut; musculoskeletal system; and skin. Orthologous to human SERPINA5 (serpin family A member 5). [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.
