Anti-TUB like protein 1 antibodies are used for the immunodetection of the protein encoded by the TULP1 gene. In humans, the canonical protein has a reported length of 542 amino acid residues and a mass of 60.6 kDa. Its subcellular localization is in the cell membrane, cytoplasm, and is secreted. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to have retina-specific expression. A member of the TUB protein family, it is reported to be required for normal development of photoreceptor synapses. The gene encoding this protein is implicated in Retinitis pigmentosa. Other names for this target antigen include RP14, TUBL1, tubby-related protein 1, tubby like protein 1, and LCA15. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species.
