GPR49 is an Orphan-A GPCR with an unknown ligand. G protein-coupled receptor GPR49 has been reported to be expressed in brain, skeletal muscle, placenta, and spinal cord. ESTs have been isolated from normal human brain (amygdala), embryo, and placenta libraries and from human germ cell, uterus, and brain (neuroblastoma) cancer libraries.Synonyms: G-protein coupled receptor 49, G-protein coupled receptor 67, G-protein coupled receptor HG38, GPR67, HG38, Leucine-rich repeat-containing G-protein coupled receptor 5
