Anti-ITPR interacting domain containing 1 antibodies are used for the immunodetection of the protein encoded by the ITPRID1 gene. In humans, the canonical protein has a reported length of 1044 amino acid residues and a mass of 115.4 kDa. Alternative splicing is reported to yield 4 different isoforms for this protein. Other names for this target antigen include ITPR-interacting domain-containing protein 1, coiled-coil domain containing 129, coiled-coil domain-containing protein 129, and protein ITPRID1. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
