Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00186
[1], [2], [3]
m6A modification ADAR1 ADAR1 METTL3 Methylation : m6A sites Direct Enhancement RNA modification MIR200B MIR200B ADAR Methylation : modification sites
m6A Modification:
m6A Regulator Methyltransferase-like 3 (METTL3) WRITER
m6A Target Interferon-inducible protein 4 (ADAR1)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> Adenosine-to-Inosine editing (A-to-I)
Epigenetic Regulator Interferon-inducible protein 4 (ADAR1) WRITER View Details
Regulated Target microRNA 200b (MIR200B) View Details
Crosstalk Relationship m6A  →  A-to-I Enhancement
Crosstalk Mechanism m6A modification directly impacts RNA modification through modulating the expression level of RNA modification regulator
Crosstalk Summary METTL3 methylates Interferon-inducible protein 4 (ADAR1) mRNA, thereby enhancing its protein expression, which subsequently promotes ADAR mediated A-to-I RNA editing of the MicroRNA 200b (MIR200B) transcript.
