G protein-coupled receptors (GPCRs), comprise a large protein family of transmembrane receptors that sense molecules outside the cell and activate inside signal transduction pathways and, ultimately, cellular responses. G protein-coupled receptors are found only in eukaryotes, including yeast, choanoflagellates, and animals. G protein-coupled receptor 32, also known as GPR32, is a human gene belonging to the rhodopsin-like subfamily of G protein-coupled receptors. GPR32 is most closely related to the chemotaxic formyl peptide receptors.
