Anti-PID1 antibodies are used in the immunodetection of the protein phosphotyrosine interaction domain containing 1. In humans, the canonical protein has a reported length of 250 amino acid residues and a mass of 28.3 kDa. Its subcellular localization is in the cytoplasm. Up to 4 different isoforms have been reported for this protein. It is reported to be expressed in subcutaneous fat, heart, skeletal muscle, brain, colon, thymus, spleen, kidney, liver, small intestine, placenta, lung and peripheral blood leukocyte. PID1 is known to be involved with cytokine-mediated signaling pathways and TNF-mediated cellular signaling pathways. Synonyms for this target antigen include NYGGF4, P-CLI1, PCLI1, PTB-containing, cubilin and LRP1-interacting protein, phosphotyrosine interaction domain-containing protein 1, and HMFN2073. PID1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PID1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
