text: The RFamide peptide family, or the RFamide-related peptides (RFRPs), are a family of neuropeptides. They are characterized by the possession of an Arg-Phe-NH motif at their C-terminal extremities.
  Members of the family include:
  * Neuropeptide FF group
  ** Neuropeptide AF
  ** Neuropeptide FF
  ** Neuropeptide SF (RFRP-1)
  ** Neuropeptide VF (RFRP-3) (GnIH - avian species)
  * Prolactin-releasing peptide (PrRP)
  * Pyroglutamylated RFamide peptide (QRFP)
  * Kisspeptin (disputed)
