Ready-to-use ELISA kits are available for the detection of GPR147, an alias of the protein, neuropeptide FF receptor 1. The official gene symbol is NPFFR1. The protein, with a mass of 47.8 kDa and length of 430 residues, is reported to be membrane-associated. It is a member of the G-protein coupled receptor 1 family and may be known by other names, including: OT7T022, NPFF1R1, GPR147, neuropeptide FF 1, RFamide-related peptide receptor OT7T022, and G-protein coupled receptor 147.
