Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00446
[1], [2], [3], [4], [5]
RNA modification MIR214 MIR214 ADARB1 Methylation : modification sites Indirect Inhibition m6A modification PTEN PTEN IGF2BP1 : m6A sites
m6A Modification:
m6A Regulator Insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1) READER
m6A Target Mutated in multiple advanced cancers 1 (PTEN)
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 A-to-I  →  m6A Inhibition
Crosstalk Mechanism RNA modification indirectly impacts m6A modification through downstream signaling pathways
Crosstalk Summary ADARB1 interacts with MicroRNA 214 (MIR214), increasing it's A-to-I level and inhibiting its physical interaction with Mutated in multiple advanced cancers 1 (PTEN), which was regulated by IGF2BP1-mediated m6A modification.
