Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00650
[1], [2], [3], [4]
m6A modification MIR221 MIR221 METTL3 Methylation : m6A sites Indirect Enhancement RNA modification FOS FOS FTO Demethylation : modification sites
m6A Modification:
m6A Regulator Methyltransferase-like 3 (METTL3) WRITER
m6A Target microRNA 221 (MIR221)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> N6,2'-O-dimethyladenosine (m6Am)
Epigenetic Regulator Fat mass and obesity-associated protein (FTO) ERASER View Details
Regulated Target Protein c-Fos (FOS) View Details
Crosstalk Relationship m6A  →  m6Am Enhancement
Crosstalk Mechanism m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary METTL3 interacts with microRNA 221 (MIR221), decreasing its m6A level and promoting its physical interaction with Protein c-Fos (FOS), which was regulated by FTO-mediated m6Am modification.
