Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00450
[1], [2], [3], [4]
m6A modification PVT1 PVT1 ALKBH5 Demethylation : m6A sites Indirect Enhancement RNA modification MIR214 MIR214 ADARB1 Methylation : modification sites
m6A Modification:
m6A Regulator RNA demethylase ALKBH5 (ALKBH5) ERASER
m6A Target Pvt1 oncogene (PVT1)
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 Double-stranded RNA-specific editase 1 (ADARB1) WRITER View Details
Regulated Target MicroRNA 214 (MIR214) View Details
Crosstalk Relationship m6A  →  A-to-I Enhancement
Crosstalk Mechanism m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary ALKBH5 interacts with Pvt1 oncogene (PVT1), increasing its m6A level and promoting its physical interaction with MicroRNA 214 (MIR214), which was regulated by ADARB1-mediated A-to-I modification.
