Gene: Hnmt (histamine N-methyltransferase) Rattus norvegicus
Symbol: Hnmt
Name: histamine N-methyltransferase
RGD ID: 71049
Description: Enables histamine N-methyltransferase activity. Involved in several processes, including histamine metabolic process; response to cocaine; and response to interleukin-1. Predicted to be located in centrosome; cytoplasm; and nucleoplasm. Predicted to be active in cytosol. Used to study brain infarction. Human ortholog(s) of this gene implicated in Parkinson's disease; asthma; atopic dermatitis; autosomal recessive intellectual developmental disorder 51; and essential tremor. Orthologous to human HNMT (histamine N-methyltransferase); PARTICIPATES IN histidine metabolic pathway; histidinemia pathway; homocysteine metabolic pathway; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 2,3,7,8-Tetrachlorodibenzofuran; ammonium chloride.
