Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00472
[1], [2], [3]
m6A modification KCNQ1OT1 KCNQ1OT1 METTL14 Methylation : m6A sites Indirect Enhancement RNA modification MIR149 MIR149 METTL1 Methylation : modification sites
m6A Modification:
m6A Regulator Methyltransferase-like 14 (METTL14) WRITER
m6A Target KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> N7-methylguanosine (m7G)
Epigenetic Regulator Methyltransferase-like protein 1 (METTL1) WRITER View Details
Regulated Target MicroRNA 149 (MIR149) View Details
Crosstalk Relationship m6A  →  m7G Enhancement
Crosstalk Mechanism m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary METTL14 interacts with KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1), increasing its m6A level and promoting its physical interaction with MicroRNA 149 (MIR149), which was regulated by METTL1-mediated m7G modification.
