This study demonstrates the involvement of ADAM10 and PI3K/Akt signaling in mediating RLX-induced Notch-1 activation.
Title: Relaxin induces up-regulation of ADAM10 metalloprotease in RXFP1-expressing cells by PI3K/AKT signaling.
Relaxin-1 mRNA in the hearts of diabetic rats was significantly increased and that relaxin-3 mRNA expression at different time points was decreased. In addition, significant down-regulation of the mRNA expression of RXFP1 and RXFP3 was observed at 4 weeks after Streptozocin.
Title: Alterations of relaxin and its receptor system components in experimental diabetic cardiomyopathy rats.
Results suggest that changes in relaxin family peptides (RXFP3, RXFP1) may contribute to the significant sex differences observed in the hippocampus and amygdala as a function of aging
Title: Sex- and age-specific differences in relaxin family peptide receptor expression within the hippocampus and amygdala in rats.
Data indicate that knee passive range of motion (ROM), relaxin receptor isoforms Rxfp1 and Rxfp2 expression were significantly reduced following treatment with testosterone, and androgen antagonist flutamide antagonized the testosterone effect.
Title: Testosterone reduces knee passive range of motion and expression of relaxin receptor isoforms via 5α-dihydrotestosterone and androgen receptor binding.
RXFP1 & RXFP2 up-regulation by progesterone and estrogen could provide the basis for the reported increase in knee laxity while down-regulation of these receptor isoforms by testosterone could explain low incidence of non-contact knee injury in male.
Title: Sex-steroid regulation of relaxin receptor isoforms (RXFP1 & RXFP2) expression in the patellar tendon and lateral collateral ligament of female WKY rats.
RXFP1 was predominantly localized to the tunica media vascular smooth muscle cells in the uterine artery. Highest expression of Rxfp1 in the uterine artery occurred in estrus and early pregnancy.

investigation of expression of RXFP1 in uterine tissues before, during, and after pregnancy; fetal-placental unit appears involved in regulation of expression of RXFP1; down-regulation of RXFP1 expression occurs in late gestation
Title: Decreased expression of the rat myometrial relaxin receptor (RXFP1) in late pregnancy is partially mediated by the presence of the conceptus.
investigation of expression of RXFP1 in myometrium during gestation; the down-regulation of RXFP1 expression that occurs in late gestation correlates well with progesterone withdrawal
Title: Progesterone withdrawal, and not increased circulating relaxin, mediates the decrease in myometrial relaxin receptor (RXFP1) expression in late gestation in rats.
Uncovered is a pre-assembled, constitutively active G-protein-coupled receptor signalosome, that couples the relaxin receptor, relaxin family peptide receptor 1 (RXFP1), to cAMP following receptor stimulation with sub-picomolar concentrations of peptide.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
