The relaxin receptors are a subclass of four closely related G protein-coupled receptors that bind relaxin peptide hormones.[1][2]

Below is list of human relaxin receptors, their endogenous peptide hormones, and what down stream enzymes are activated or inhibited by the receptor.

receptor/gene ligands activates inhibits
RXFP1 Relaxin 1, Relaxin 2, Relaxin 3 adenylate cyclase, protein kinase A, protein kinase C,

phosphatidylinositol 3-kinase, extracellular signal-regulated kinases (Erk1/2)

RXFP2 Relaxin 1, Relaxin 2, INSL3 adenylate cyclase
RXFP3 Relaxin 3 Erk1/2 signaling adenylate cyclase
RXFP4 Relaxin 3, INSL3 adenylate cyclase
