Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00467
[1], [2], [3]
RNA modification MIR149 MIR149 ADAR Methylation : modification sites Indirect Enhancement m6A modification HMGA2 HMGA2 METTL14 Methylation : m6A sites
m6A Modification:
m6A Regulator Methyltransferase-like 14 (METTL14) WRITER
m6A Target High mobility group protein HMGI-C (HMGA2)
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 149 (MIR149) View Details
Crosstalk Relationship A-to-I  →  m6A Enhancement
Crosstalk Mechanism RNA modification indirectly impacts m6A modification through downstream signaling pathways
Crosstalk Summary ADAR1 interacts with MicroRNA 149 (MIR149), increasing it's A-to-I level and promoting its physical interaction with High mobility group protein HMGI-C (HMGA2), which was regulated by METTL14-mediated m6A modification.
