Summary
HEMK2 (HemK methyltransferase 2, ETF1 glutamine and histone H4 lysine, HGNC:16021) is a protein-coding gene on chromosome 21q21.3, encoding Methyltransferase HEMK2 (Q9Y5N5). Methyltransferase that can methylate proteins and, to a lower extent, arsenic. It is a selective cancer dependency (DepMap: 52.4% of cell lines).
This gene encodes an N(6)-adenine-specific DNA methyltransferase. The encoded enzyme may be involved in the methylation of release factor I during translation termination. This enzyme is also involved in converting the arsenic metabolite monomethylarsonous acid to the less toxic dimethylarsonic acid. Alternative splicing of this gene results in multiple transcript variants. A related pseudogene has been identified on chromosome 11.

- N6AMT1 converted monomethylarsonous acid to dimethylarsonic acid when overexpressed in UROtsa human urothelial cells. It is expressed in many human tissues at variable levels, supporting a potential participation in arsenic metabolism in vivo. (PMID:21193388)
- Five N6AMT1 single nucleotide polymorphisms and two N6AMT1 haplotypes were significantly associated with the percentage of methylarsonic acid in urine, even after adjusting for arsenic (+3 oxidation state) methyltransferase haplotype. (PMID:23665909)
- combined effect of N6AMT1 haplotype 2_GGCCAT and As3MT haplotype 2_GCAC showed consistence with the additive significance of each haplotype on % iAs: the mean was 5.47% and 9.36% for carriers with both and null haplotypes, respectively (PMID:27637898)
- AS3MT and N6AMT1 polymorphisms and urinary arsenic metabolites (%iAs, %MMA, %DMA) in 722 subjects from an arsenic-cancer case-control study in a uniquely exposed area in northern Chile, were examined. (PMID:28640505)
- The abundance of 6mA was significantly lower in cancers, accompanied by decreased N6AMT1 and increased ALKBH1 levels, and downregulation of 6mA modification levels promoted tumorigenesis. Collectively, Results demonstrate that DNA 6mA modification is extensively present in human cells and the decrease of genomic DNA 6mA promotes human tumorigenesis. (PMID:30017583)

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.
Subunit / interactions. Heterodimer; heterodimerization with TRMT112 is required for S-adenosyl-L-methionine-binding. Does not interact with TRMT112.
Subcellular location. Nucleus.
Tissue specificity. Widely expressed, with highest expression in parathyroid and pituitary glands, followed by adrenal gland and kidney, and lowest expression in leukocytes and mammary gland.
Post-translational modifications. Ubiquitinated, leading to its degradation by the proteasome. Ubiquitinated, leading to its degradation by the proteasome.
Similarity. Belongs to the eukaryotic/archaeal PrmC-related family.
