Also known as: Rln; rlx
Summary: Enables signaling receptor binding activity. Involved in mammary gland development; regulation of apoptotic process; and spermatogenesis. Acts upstream of or within prostate gland growth and regulation of nitric oxide mediated signal transduction. Predicted to be located in extracellular region. Is expressed in several structures, including Harderian gland; alimentary system; genitourinary system; immune system; and liver and biliary system. Orthologous to human RLN1 (relaxin 1) and RLN2 (relaxin 2). [provided by Alliance of Genome Resources, Jan 2025]

In summary, relaxin deficiency results in increased cervical collagen in late pregnancy, which is not explained by a reduction in Mmp expression or activity or decreased Rxfp1.
Title: Abnormal extracellular matrix remodelling in the cervix of pregnant relaxin-deficient mice is not associated with reduced matrix metalloproteinase expression or activity.
the data demonstrate that pregnant Rln(-/-) mice do not have the typical characteristics of preeclampsia. However, these mice show evidence of proteinuria, but we suggest that this results from systemic renal vascular dysfunction before pregnancy.

The digestive tract has been shown to express relaxin receptors; the hormone appears to exert site-specific effects acting at the neural or at the smooth muscle level, mainly by a nitric oxide-mediated mechanism. (Review)

we demonstrate endothelial dysfunction and impaired arterial wall remodeling in male mice deficient in relaxin. Thus, our results highlight a role for endogenous relaxin in the maintenance of normal mesenteric artery structure and function in males.

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.
