Melatonin receptor type 1B (UniProt: P49286; also known as Mel-1B-R; Mel1b receptor) is encoded by the gene MTNR1B gene (Gene ID 4544) in human. Mel-1B-R is a high affinity receptor for melatonin that belongs to the G-protein coupled receptor 1 family. Mel-1B mediates the reproductive and circadian actions of melatonin. Melatonin is shown to be involved in body mass regulation in mammals and this effect is suggest to be mediated by a direct action of melatonin on Mel-1B receptors on brown adipocytes. Melatonin also acts as a chemopreventive agent and its levels inversely correlate with the risk of developing cancer. In this regard melatonin induces p38-dependent phosphorylation of both p53 and histone H2AX. Activation of the p53-dependent DNA damage response by melatonin is mediated by both Mel-1A and Mel-1B receptors. The absence of either receptor impairs melatonin′s ability to reduce both cell proliferation and clonogenic potential of cancer cells. (Brydon, L. et al. (2001).
