24641548 we demonstrated distinct patterns of signalling for H3 and H2 relaxin and R3(BDelta23-27)R/I5 at the RXFP3 receptor
24615237 Glu141 and Asp145 of the RXFP3 interact with the highly conserved arginine residues of relaxin-3.
22347403 demonstrate the existence of an allosteric site for modulation of RXFP3
20211485 Methylation status of CIDEA, HAAO and RXFP3 had significant association with microsatellite instability in endometrial tumors.
20159943 H3 relaxin potently activates all signaling pathways coupled to RXFP3, whereas H2 relaxin is an AP-1-biased ligand relative to H3 relaxin.
19152634 Results decribe the structural and functional aspects of the interaction between relaxin-3 and its receptor, RXFP3.
18582868 the N-terminus and EL2 domains of RXFP3 and RXFP4 are involved in ligand binding while TM2, 3, and 5 are critical for receptor activation.
18434306 analysis of truncated human relaxin-2 and -3 (H2 and H3) relaxin peptides and their binding and cAMP activities on RXFP1, RXFP2, and RXFP3
15956730 functional response to H3 relaxin and other relaxin/insulin peptides of GPCR135 expressed in CHO-K1 cells was measured in the cytosensor microphysiometer and analyzed using inhibitors of signal transduction proteins
15465925 Substitution of the relaxin-3 A-chain with the A-chain from insulin-like peptide 5 results in a chimeric peptide that selectively activates GPCR135 and GPCR142.
14522968 GPCR135 (SALPR) is the receptor for relaxin-3
