HGNC Approved Gene Symbol: GPR21
Cytogenetic location: 9q33.2 Genomic coordinates (GRCh38): 9:123,033,667-123,049,103 (from NCBI)
O'Dowd et al. (1997) isolated 4 novel human putative G protein-coupled receptor (GPCR) genes: GPR20 (601908), GPR21, GPR22 (601910), and GPR23 (LPAR4; 300086). All 4 contain the 7 putative transmembrane regions characteristic of GPCRs. Their deduced proteins share significant sequence identity to each other and to other members of the GPCR family.
O'Dowd et al. (1997) mapped the GPR21 gene to chromosome 9q33 by fluorescence in situ hybridization.
