relaxin peptide Exhibits correct molecular weight - Peptides relaxin Unraveling the Complexity of the Relaxin Peptide Family: Structure, Function, and Therapeutic Potential

Peptides The relaxin peptide family represents a fascinating group of hormones with diverse and far-reaching physiological roles. Belonging to the superfamily of insulin peptides, these seven cystine-rich peptides are structurally related to insulin and play significant roles in both reproduction and non-reproductive functionsRelaxin is a peptide hormoneproduced by the corpus luteum and placenta during pregnancy, which plays a role in maintaining early pregnancy, ripening the cervix .... While commonly associated with pregnancy, the broader implications of relaxin and its related peptides extend to cardiovascular, metabolic, and neurological health, underscoring their importance as peptide signaling molecules.

At its core, the human relaxin peptide family comprises seven distinct members. These include three relaxin-like (RLN) peptides – specifically Relaxin-1, Relaxin-2, and Relaxin-3 – and four insulin-like (INSL) peptides: INSL-3, INSL-4, INSL-5, and INSL-6Relaxin: A Peptide with Promising Therapeutic Applications. This intricate network of peptides signals through specific receptors, primarily Relaxin Family Peptide Receptor 1 (RXFP1) and Relaxin Family Peptide Receptor 2 (RXFP2), which are G protein-coupled receptors (GPCRs).INSL5 is apeptidehormone from therelaxinsuperfamily, which includes insulin, insulin-like growth factors, relaxins and insulin-likepeptides. Relaxin (RLN2, P04090), for instance, is well-established as the cognate peptide ligand for RXFP1, mediating a range of beneficial effects.The relaxin family peptide hormones belong to the insulin superfamily andconsists of seven peptides...

The structural hallmark of these peptides is a conserved fold characterized by two polypeptide chains, an A-chain and a B-chain, held together by three disulfide bonds作者：Z Huang·2015·被引用次数：25—Relaxin peptide(RLN), which signals through the relaxin family peptide 1 (RXFP1) GPCR receptor, has shown therapeutic effects in an acute heart failure .... This intricate structure is crucial for their biological activity. For example, Human Relaxin-2, also called H2 Relaxin, is a 6 kDa, 53 amino acid heterodimeric polypeptide with significant roles in female reproductive physiology. While Relaxin-2 is a clinically relevant peptide agonist for RXFP1, research continues to explore its potential for therapeutic applications, aiming to enhance its duration of action and improve its pharmacokinetic profile for daily administration.

The physiological functions of the relaxin peptide family are remarkably diverse and broadly expressed in the body. During pregnancy, relaxin is a pivotal hormone.作者：NA Patil·2017·被引用次数：95—The human relaxin peptide family consists ofseven cystine-rich peptides, four of which are known to signal through relaxin family peptide ... It is produced by organs such as the ovary, corpus luteum, and placenta and plays a critical role in preparing the body for childbirth.Relaxin-2Peptide≥98% (HPLC), human recombinant, expressed in E. coli, suitable for cell culture Synonyms: H2relaxin,RLN2 at Sigma-Aldrich. Actions include softening and ripening the cervix, elongating the pubic symphysis, and inhibiting uterine contractions, all contributing to a successful pregnancy and parturition. This role in cervical ripening and induction of labor has been a subject of clinical investigation.

Beyond reproduction, research has illuminated the pleiotropic nature of relaxin and its related peptides. Relaxin exhibits potent vasodilatory, anti-fibrotic, angiogenic, anti-apoptotic, and anti-inflammatory effects. These properties suggest therapeutic potential in cardiovascular diseases, such as acute heart failure, where relaxin peptide signaling through RXFP1 has demonstrated beneficial outcomes. Furthermore, the relaxin peptide family's influence extends to metabolic regulation and neurological function, indicating a much broader physiological scope than previously understood. For instance, Relaxin-3 (RNL3), identified as one of the seven peptides of Relaxin, is expressed in neurons of the brain stem, hinting at its role in central nervous system processesThe relaxin family peptide hormones belong to the insulin superfamily andconsists of seven peptides...
