FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Members of family C of the G protein-coupled receptor (GPCR) superfamily, such as GPRC6A, are characterized by an evolutionarily conserved amino acid-sensing motif linked to an intramembranous 7-transmembrane loop region. Several members of GPCR family C, including GPRC6A, also have a long N-terminal domain (summary by Pi et al., 2005 [PubMed 16199532]).[supplied by OMIM, Nov 2010]
PHENOTYPE: Mice homozygous for a knock-out allele show a metabolic syndrome characterized by impaired bone mineralization, increased fat mass, abnormal renal handling of calcium and phosphorus, fatty liver, glucose intolerance, testicular feminization and abnormal steroidogenesis.

Protein Function and Prediction

GPRC6A is a member of the C family of G-protein-coupled receptors that sense amino acid and extracellular cations (1;2). GPRC6A senses extracellular amino acids, osteocalcin, and divalent cations in bone (3).  At the cell surface, GPRC6A couples to inositol 1,4,5-triphosphate production to facilitate the release of calcium from intracellular stores (2). Using a knockout model, Pi et al. (2010) determined that GRPC6A also functions in the regulation of osteoblast-mediated bone mineralization (3).


GPRC6A is expressed in skeletal muscle, brain, leukocytes, and kidney (4). In humans there are three GPRC6A isoforms. Isoform-1 is highest in brain, skeletal muscle, testis, and leukocytes, with lower expression in liver, heart, kidney, and spleen, and weak expression in lung, pancreas, placenta, and ovary (4). Isoforms-1 and -2 are equally expressed in the kidney (4).  Isoforms-2 and -3 are generally weakly expressed, compared to isoform-1 (4). In mouse tissues, Gprc6a is expressed in all tissues examined (1). In rat tissues, Gprc6a is ubiquitously expressed, with highest expression in the soft palate (5). In HEK293 cells, a transfected epitope-tagged human GPRC6A was expressed at the cell surface (1).


Gprc6a knockout mice have a decrease in bone mineral density and reduced expression of osteocalcin, ALP, osteoprotegerin, and Runx2-II transcripts in bone (3). Osteoblasts and BMSCs from the knockout animals had attenuated responses upon ERK activation, diminished alkaline phosphatase (ALP) expression, and impaired mineralization ex vivo (3). Loss of Grpc6a is also associated with glucose intolerance, hepatic steatosis, abnormal steroid biogenesis, and osteopenia (3).

Mice homozygous for a knock-out allele show a metabolic syndrome characterized by impaired bone mineralization, increased fat mass, abnormal renal handling of calcium and phosphorus, fatty liver, glucose intolerance, testicular feminization and abnormal steroidogenesis (6).
