Relaxin-3 (RNL3) is one of the 7 peptides of Relaxin which is an insulin-related peptide hormone.1 Relaxin 3 is expressed in neurons of the brain stem that inneravate wide areas of the forebrain. Relaxin 3 mRNA levels in these neurons are increased in response to restraint stress, and by central administration of corticotropin-releasing factor (CRF).2 Relaxin-3 may act as a central signal linking nutritional status and reproductive function.3
