Relaxin/insulin-like family peptide receptor 1

Relaxin/insulin-like family peptide receptor 1, also known as RXFP1, is a human G protein coupled receptor that is one of the relaxin receptors.^[5] It is a rhodopsin-like GPCR which is unusual in this class as it contains a large extracellular binding and signalling domain.^[6] Some reports suggest that RXFP1 forms homodimers,^[7][8] however the most recent evidence indicates that relaxin binds a non-homodimer of RXFP1.^[9][10]
