Anti-TPD52 like 3 antibodies are used for the immunodetection of the protein encoded by the TPD52L3 gene. In humans, the canonical protein has a reported length of 140 amino acid residues and a mass of 15.5 kDa. Alternative splicing is reported to yield 3 different isoforms for this protein. It is notably expressed in the testis. It is a member of the TPD52 protein family. Other names for this target antigen include protein kinase NYD-SP25, testis development protein NYD-SP25, testis tissue sperm-binding protein Li 87P, tumor protein D52 like 3, and tumor protein D55. Gene orthologs have been identified in the mouse, rat, bovine and chimpanzee species.
