UniProtKB - Q5R5V8 (RXFP1_PONAB)
Protein
Relaxin receptor 1
Gene
RXFP1
Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
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 similarity
