Anti-NPYR antibodies enable researchers to detect and measure the NPYR antigen in biological samples. This target is a reported synonym of the NPY1R gene, which encodes neuropeptide Y receptor Y1. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of NPYR has a canonical amino acid length of 384 residues and a protein mass of 44.4 kilodaltons. It is reported to be localized in the cell membrane of cells. NPYR is a member of the G-protein coupled receptor 1 protein family.
