Related Product Information for HNMT active protein

Description: HNMT Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 328 amino acids (1-292 a.a) and having a molecular mass of 37.4kDa.HNMT is fused to a 36 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Introductions: Histamine N-Methyltransferase or HNMT, is located in the cell cytosol. Sadenosyl-L-methionine acts as a methyl donor for HNMT which inactivates histamine. By inactivation of histamine, it affects the immune system's response. HNMT acts on histamine in body tissues such as kidney, central nervous system and bronchus. The protein has a crucial part in the airway response to histamine & histamine degradation process and regulation.

NCBI Description

In mammals, histamine is metabolized by two major pathways: N(tau)-methylation via histamine N-methyltransferase and oxidative deamination via diamine oxidase. This gene encodes the first enzyme which is found in the cytosol and uses S-adenosyl-L-methionine as the methyl donor. In the mammalian brain, the neurotransmitter activity of histamine is controlled by N(tau)-methylation as diamine oxidase is not found in the central nervous system. A common genetic polymorphism affects the activity levels of this gene product in red blood cells. Multiple alternatively spliced transcript variants that encode different proteins have been found for this gene. [provided by RefSeq, Jul 2008]

Uniprot Description

Inactivates histamine by N-methylation. Plays an important role in degrading histamine and in regulating the airway response to histamine.
