G protein-coupled receptor 1, also known as GPR1, is a protein that in humans is encoded by the GPR1 gene.^[5]^[6]

GPR1 is a member of the G protein-coupled receptor family of transmembrane receptors. It functions as a receptor for chemerin.^[7] Other receptors for chemerin include CMKLR1 and CCRL2.
