Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00430
[1], [2], [3], [4], [5]
m6A modification MEG3 MEG3 METTL3 Methylation : m6A sites Indirect Inhibition RNA modification MIR21 MIR21 ADAR Methylation : modification sites
m6A Modification:
m6A Regulator Methyltransferase-like 3 (METTL3) WRITER
m6A Target Maternally expressed 3 (MEG3)
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 21 (MIR21) View Details
Crosstalk Relationship m6A  →  A-to-I Inhibition
Crosstalk Mechanism m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary METTL3 interacts with Maternally expressed 3 (MEG3), increasing its m6A level and inhibiting its physical interaction with MicroRNA 21 (MIR21), which was regulated by ADAR1-mediated A-to-I modification.
