Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00519
[1], [2], [3]
RNA modification MIR221 MIR221 ADARB1 Methylation : modification sites Indirect Inhibition m6A modification FOS FOS FTO Demethylation : m6A sites
m6A Modification:
m6A Regulator Fat mass and obesity-associated protein (FTO) ERASER
m6A Target Protein c-Fos (FOS)
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 221 (MIR221) 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 221 (MIR221), increasing it's A-to-I level and inhibiting its physical interaction with Protein c-Fos (FOS), which was regulated by FTO-mediated m6A modification.
