Anti-solute carrier family 49 member 4 antibodies are used for the immunodetection of the protein encoded by the SLC49A4 gene. In humans, the canonical protein has a reported length of 478 amino acid residues and a mass of 52.1 kDa. Its subcellular localization is in the lysosomes. Alternative splicing is reported to yield 2 different isoforms for this protein. It is ubiquitously expressed across many tissue types. It is a member of the Major facilitator protein superfamily. Post-translational modifications have been described, including N-glycosylation and protein cleavage. Other names for this target antigen include disrupted in renal carcinoma 2, renal cell carcinoma 4, and disrupted in renal cancer protein 2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
