Family

FMRFamide-related peptide/Growth hormone-releasing peptide (IPR026297)

Short name: FMRFamide-related/fGRP

Family relationships

None.

Description

This family includes both FMRFamide-related peptides and growth hormone-releasing peptides.

FMRFamide-related peptides are neurotransmitters, hormone-like substances and tumor suppressor peptides [PMID: 21524675]. Neuropeptide RFRP-1 acts as a potent negative regulator of gonadotropin synthesis and secretion. Neuropeptides NPSF and NPVF efficiently inhibit forskolin-induced production of cAMP, but RFRP-2 shows no inhibitory activity. Neuropeptide NPVF blocks morphine-induced analgesia. FMRFamide-related peptides may act in concert with kisspeptin, through opposing affects, to regulate the activity of gonadotropin-releasing hormone (GnRH) neurons across the seasons, leading to an annual change in fertility and the cyclical seasonal transition from non-breeding to breeding season [PMID: 18617612, PMID: 18617613, PMID: 9808777].

The primary role of growth hormone-releasing peptide (fGRP) is to release GH from the pituitary [PMID: 11796493].
