Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00498
[1], [2], [3]
RNA modification MIR222 MIR222 ADAR Methylation : modification sites Indirect Inhibition m6A modification CDKN1B CDKN1B METTL14 Methylation : m6A sites
m6A Modification:
m6A Regulator Methyltransferase-like 14 (METTL14) WRITER
m6A Target Cyclin-dependent kinase inhibitor 1B (CDKN1B/p27)
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 222 (MIR222) View Details
Crosstalk Relationship A-to-I  →  m6A Inhibition
Crosstalk Mechanism RNA modification indirectly impacts m6A modification through downstream signaling pathways
Crosstalk Summary ADAR1 interacts with MicroRNA 222 (MIR222), increasing it's A-to-I level and inhibiting its physical interaction with Cyclin-dependent kinase inhibitor 1B (CDKN1B/p27), which was regulated by METTL14-mediated m6A modification.
