Crosstalk ID
M6ACROT00471
[1], [2], [3]
m6A modification KCNQ1OT1 KCNQ1OT1 METTL14 Methylation : m6A sites Indirect Enhancement RNA modification MIR149 MIR149 ADAR 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)  >> 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 m6A  →  A-to-I 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 ADAR1-mediated A-to-I modification.
