  • Function

    N6-methyltransferase that methylates adenosine residues of some mRNAs. N6-methyladenosine (m6A), which is present at internal sites of some mRNAs, may play a role in the efficiency of mRNA splicing, transport or translation.
  • Tissue specificity

    Widely expressed at low level. Expressed in spleen, thymus, prostate, testis, ovary, small intestine, colon and peripheral blood leukocytes.
  • Sequence similarities

    Belongs to the MT-A70-like family.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Nucleus speckle. Colocalizes with speckles in interphase nuclei. Suggesting that it may be associated with nuclear pre-mRNA splicing components.
