RN [2] RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA]. RC TISSUE=Embryo; RG NIH - Xenopus Gene Collection (XGC) project; RL Submitted (AUG-2004) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Dioxygenase that demethylates RNA by oxidative CC demethylation: specifically demethylates N(6)-methyladenosine CC (m6A) RNA, the most prevalent internal modification of messenger CC RNA (mRNA) in higher eukaryotes. Can also demethylate N(6)- CC methyladenosine in single-stranded DNA (in vitro) (By similarity). CC Requires molecular oxygen, alpha-ketoglutarate and iron (By CC similarity). Demethylation of m6A mRNA affects mRNA processing and CC export (By similarity). {ECO:0000250|UniProtKB:Q3TSG4, CC ECO:0000250|UniProtKB:Q6P6C2}. CC -!- CATALYTIC ACTIVITY: N(6)-methyladenosine in mRNA + 2-oxoglutarate CC + O(2) = adenosine in mRNA + formaldehyde + succinate + CO(2). CC {ECO:0000250|UniProtKB:Q6P6C2}. CC -!- COFACTOR: CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033; CC Evidence={ECO:0000250|UniProtKB:Q6P6C2}; CC Note=Binds 1 Fe(2+) ion per subunit. CC {ECO:0000250|UniProtKB:Q6P6C2}; CC -!- SUBCELLULAR LOCATION: Nucleus speckle CC {ECO:0000250|UniProtKB:Q6P6C2}. CC -!- SIMILARITY: Belongs to the alkB family. {ECO:0000305}.
