  N (6) -adenine-specific methyltransferase that can methylate both RNAs and DNA. Acts as a N (6) -adenine-specific RNA methyltransferase by catalyzing formation of N6,2'-O-dimethyladenosine (m6A (m) ) on internal positions of U2 small nuclear RNA (snRNA) : methylates the 6th position of adenine residues with a pre-deposited 2'-O-methylation. Internal m6A (m) methylation of snRNAs regulates RNA splicing. Also able to act as a N (6) -adenine-specific DNA methyltransferase by mediating methylation of DNA on the 6th position of adenine (N (6) -methyladenosine) . The existence of N (6) -methyladenosine (m6A) on DNA is however unclear in mammals, and additional evidences are required to confirm the role of the N (6) -adenine-specific DNA methyltransferase activity of METTL4 in vivo. Acts as a regulator of mitochondrial transcript levels and mitochondrial DNA (mtDNA) copy number by mediating mtDNA N (6) -methylation: m6A on mtDNA reduces transcription by repressing TFAM DNA-binding and bending. N (6) -methyladenosine deposition by METTL4 regulates Polycomb silencing by triggering ubiquitination and degradation of sensor proteins ASXL1 and MPND, leading to inactivation of the PR-DUB complex and subsequent preservation of Polycomb silencing.

• Endotoxin:

  Not test

• Purity:

  Greater than 85% as determined by SDS-PAGE.

• Activity:

  Not Test

• Form:

  Liquid or Lyophilized powder

• Buffer:

  If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

• Reconstitution:

  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

• Storage Conditions:

  The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
