Anti-DOP1A antibodies are used in the immunodetection of the protein DOP1 leucine zipper like protein A. In humans, the canonical protein has a reported length of 2465 amino acid residues and a mass of 277.4 kDa. Its subcellular localization is in the Golgi and membrane. It is notably widely expressed in many tissue types. A member of the Dopey protein family, DOP1A is suspected to be involved in protein traffic between late Golgi and early endosomes. Synonyms for this target antigen include DOPEY1, KIAA1117, dJ202D23.2, protein dopey-1, dopey family member 1, homolog of yeast DOP1, and DOP1. DOP1A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
