Leucine-rich repeat-containing G protein-coupled receptor 4

LGR4, GPR48, G protein-coupled receptor 48
G protein-coupled receptors (GPCRs) play key roles in a variety of physiologic functions. Members of the leucine-rich GPCR (LGR) family, such as GPR48, have multiple N-terminal leucine-rich repeats (LRRs) and a 7-transmembrane domain (Weng et al., 2008 [PubMed 18424556]).[supplied by OMIM, Aug 2008] (from NCBI)
