Background: The relaxin family peptide receptor RXFP2, also known as LGR8, is a 754-amino acid 7 transmembrane protein. RT-PCR detected RXFP2 expression in various organs of the reproductive system along with the brain, kidney, thyroid, muscle, peripheral blood cell, and bone marrow. RXFP2 is known to be important in supporting germ cell function in the testis and ovaries. Additionally, RXFP2 mutations are linked to osteoporosis in men, suggesting that it plays a central role in bone physiology.
