Gene: Mtnr1b (melatonin receptor 1B) Rattus norvegicus
Analyze
Symbol: Mtnr1b
Name: melatonin receptor 1B
RGD ID: 620798
Description: Predicted to enable melatonin receptor activity. Involved in several processes, including negative regulation of cell communication; positive regulation of circadian sleep/wake cycle, non-REM sleep; and regulation of transmission of nerve impulse. Predicted to be active in plasma membrane. Used to study acute pancreatitis. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Orthologous to human MTNR1B (melatonin receptor 1B); INTERACTS WITH ammonium chloride; benzo[a]pyrene; flavonoids.
Type: protein-coding
RefSeq Status: VALIDATED
Previously known as: mel-1B-R; mel1b melatonin receptor; mel1b receptor; Mel1b-r; melatonin receptor type 1B; Mt2
