Does Kisspeptin Belong to the Proposed RF-Amide Peptide Family?
Kisspeptin (KISS) plays a key role in regulating reproduction by binding to its receptor, GPR54. Because of the Arg-Phe (RF) sequence at its carboxyl terminus, KISS has been proposed to be a member of the RF-amide peptide family consisting of neuropeptide FF (NPFF), neuropeptide VF (NPVF), pyroglutamylated RF-amide peptide (QRFP), and prolactin-releasing hormone (PRLH). Evolutionary relationshi...
متن کاملDistribution and regulation of gonadotropin-releasing hormone, kisspeptin, RF-amide related peptide-3, and dynorphin in the bovine hypothalamus.
Recent work has led to the hypothesis that kisspeptin/neurokinin B/dynorphin (KNDy) neurons in the arcuate nucleus (ARC) play a key role in gonadotropin-releasing hormone (GnRH) pulse generation and gonadal steroid feedback, with kisspeptin driving GnRH release and neurokinin B and dynorphin acting as pulse start and stop signals, respectively. A separate cell group, expressing RFamide-related ...
متن کاملEditorial: A Comparative Survey of the RF-Amide Peptide Superfamily
The first member of the RF-amide peptide superfamily to be characterized, in 1977, was the cardioexcitatory peptide, FMRFamide, isolated from the ganglia of the clamMacrocallista nimbosa (1). Since then, a large number of such peptides, designated after their C-terminal arginine (R) and amidated phenylalanine (F) residues, have been identified in representative species of all major phyla. The d...
متن کاملP-21: RF-Amide Related Peptide mRNA Expression in Male Rat Dorsomedial Hypothalamic Nucleus during Chronic Stress
Background Chronic stress induces male reproductive dysfunction; however, the involved mechanisms are not clear. It has been suggested that the gonadotrophin-inhibitory hormone, known as RF-amide related peptide (RFRP) in mammalian species, may mediate this inhibitory effect of stress. The objective of the present study was to compare the effect of chronic stress and glucocorticoids receptor an...
