Probable G-protein coupled receptor 45 is a protein that in humans is encoded by the GPR45gene.[5][6]
This intronless gene encodes a member of the G protein-coupled receptor (GPCR) family. Members of this protein family contain seven putative transmembrane domains and may mediate signaling processes to the interior of the cell via activation of heterotrimeric G proteins. This protein may function in the central nervous system.[6]
