Product Overview
Tag | His |
Host Species | Human |
Accession | AAH11554.1 |
Synonym | C21orf127, HEMK2, m.HsaHemK2P, MTQ2, N6AMT, PRED28 |
Background | N6AMT1 has a significant role in determining susceptibility to arsenic toxicity and carcinogenicity because of its specific activity in methylating MMAIII to DMA and other unknown mechanisms.N6AMT1 polymorphisms were associated with arsenic methylation in Andean women, independent of AS3MT. N6AMT1 polymorphisms may be susceptibility markers for arsenic-related toxic effects.N-6 adenine-specific DNA methyltransferase 1 (N6AMT1) also methylates the toxic inorganic arsenic (iAs) metabolite, monomethylarsonous acid (MMA), to the less toxic dimethylarsonic acid (DMA). |
Description | A DNA sequence encoding the mature form of human N6AMT1 (AAH11554.1) (Met 1-Ser 186) was fused with a His tag at the C-terminus. |
Source | E.coli |
Predicted N Terminal | Met 1 |
AA Sequence | Met 1-Ser 186 |

Target Details
Target Function | Methyltransferase that can methylate proteins and, to a lower extent, arsenic. Catalytic subunit of a heterodimer with TRMT112, which monomethylates 'Lys-12' of histone H4 (H4K12me1), a modification present at the promoters of numerous genes encoding cell cycle regulators. Catalytic subunit of a heterodimer with TRMT112, which catalyzes N5-methylation of Glu residue of proteins with a Gly-Gln-Xaa-Xaa-Xaa-Arg motif. Methylates ETF1 on 'Gln-185'; ETF1 needs to be complexed to ERF3 in its GTP-bound form to be efficiently methylated. May also play a role in the modulation of arsenic-induced toxicity by mediating the conversion of monomethylarsonous acid (3+) into the less toxic dimethylarsonic acid. It however only plays a limited role in arsenic metabolism compared with AS3MT. |
