Anti-OXA1L mitochondrial inner membrane protein antibodies are used for the immunodetection of the protein encoded by the OXA1L gene. In humans, the canonical protein has a reported length of 435 amino acid residues and a mass of 48.5 kDa. Its subcellular localization is in the mitochondria. Alternative splicing is reported to yield 3 different isoforms for this protein. A member of the OXA1/ALB3/YidC protein family, it is known to be required for the insertion of integral membrane proteins into the mitochondrial inner membrane. Other names for this target antigen include OXA1L1, mitochondrial inner membrane protein OXA1L, OXA1-like protein, epididymis secretory sperm binding protein, oxidase (cytochrome c) assembly 1-like, and OXA1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
