UniProtKB - Q6R6I6 (RXFP1_RAT)
Protein
Relaxin receptor 1
Gene
Rxfp1
Organism
Rattus norvegicus (Rat)
Status
Functioni
Receptor for relaxins. The activity of this receptor is mediated by G proteins leading to stimulation of adenylate cyclase and an increase of cAMP. Binding of the ligand may also activate a tyrosine kinase pathway that inhibits the activity of a phosphodiesterase that degrades cAMP (By similarity).By similarity1 Publication
