Anti-DOR antibodies are protein reagents that detect specific antigens. The DOR antigen is another term for the human protein opioid receptor delta 1, encoded by the OPRD1 gene. The protein is known to function in the cellular response to hypoxia and GPCR signaling pathways, among other biological roles. Canonically, it has an amino acid length of 372 residues and a mass of 40.4 kilodaltons. Its subcellular localization is in the cell membrane and it is notably expressed in oocytes. The DOR protein is a member of the G-protein coupled receptor 1 protein family. Other alias names for DOR include DOP and DOR1. ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for DOR antibodies.
