These GPR74 ELISA kits are immunodetection tools for measuring the levels of GPR74 in biological samples. GPR74 is an alias of the human NPFFR2 gene, which encodes the protein, neuropeptide FF receptor 2. Notably, GPR74 is known to play a role in GPCR signaling pathways, among other functions. The NPFFR2 protein is 522 amino acid residues in length and 60.3 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the cell membrane of the cell. This protein is known to be glycosylated. Other names for this target antigen include HLWAR77.
