G-protein coupled receptor family C group 6 member A is a protein that in humans is encoded by the GPRC6A gene.^[1] This receptor functions as a sensor of L-amino acids,^[2] calcium,^[3] osteocalcin,^[4] and steroids.^[5]

Clinical significance[edit]

GPRC6A has also been linked to prostate cancer progression, and it has been shown to mediated rapid, non-genomic prostate cancer cell responses to testosterone.^[6]
