Anti-CLINT1 antibodies are used in the immunodetection of the protein clathrin interactor 1. In humans, the canonical protein has a reported length of 625 amino acid residues and a mass of 68.3 kDa. Its subcellular localization is in the membrane, cytoplasmic vesicles, and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is found to be widely expressed at low to intermediate levels. A member of the Epsin protein family, CLINT1 is known to bind to membranes enriched in phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2). Synonyms for this target antigen include ENTH, EPN4, EPNR, clathrin interacting protein localized in the trans-Golgi region, enthoprotin, and CLINT. CLINT1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
