Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00598
[1], [2], [3], [4], [5], [6]
m6A modification MIR21 MIR21 METTL3 Methylation : m6A sites Indirect Enhancement RNA modification PTEN PTEN TET1 Demethylation : modification sites
m6A Modification:
m6A Regulator Methyltransferase-like 3 (METTL3) WRITER
m6A Target microRNA 21 (MIR21)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> 5-methylcytidine (m5C)
Epigenetic Regulator Methylcytosine dioxygenase TET1 (TET1) ERASER View Details
Regulated Target Mutated in multiple advanced cancers 1 (PTEN) View Details
Crosstalk Relationship m6A  →  m5C Enhancement
Crosstalk Mechanism m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary METTL3 interacts with microRNA 21 (MIR21), decreasing its m6A level and promoting its physical interaction with Mutated in multiple advanced cancers 1 (PTEN), which was regulated by TET1-mediated m5C modification.
