Anti-ENTR1 antibodies are used in the immunodetection of the protein endosome associated trafficking regulator 1. In humans, the canonical protein has a reported length of 435 amino acid residues and a mass of 48 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 the colon. A member of the ENTR1 protein family, ENTR1 is reported to be an endosome-associated protein that plays a role in membrane receptor sorting, cytokinesis and ciliogenesis. Synonyms for this target antigen include SDCCAG3, SDDAG3, antigen NY-CO-3, serologically defined colon cancer antigen 3, and NY-CO-3. ENTR1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ENTR1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
