General information
Histamine N-methyltransferase is one of the two enzymes involved in the metabolism of histamine in mammals, this is known as the N(tau)-methylation pathway. The second pathway is oxidative deamination via diamine oxidase (DAO). This protein is encoded by the gene HNMT and it can be found in the cytosol intracellular fluid. HNMT is expressed in many organs like liver, kidney and brain, being found in most of the body tissues, except for serum. (Yoshikawa, 2019)
Funtion of HNMT is catalyzation of histamine methylation in the presence of S-adenosylmethionine (SAM-e) yielding N-methylhistamine. Histamine (HA) is inactivated by using S-adenosylmethionine (SAM-e) as a methyl donor. This occurs, as an example, during the termination process of neurotransmission actions of HA in the mammalian central nervous system.(Heidari, 2015 Yoshikawa, 2019)
