Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00510
[1], [2], [3], [4]
RNA modification MIR18A MIR18A ADAR Methylation : modification sites Indirect Enhancement 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 Interferon-inducible protein 4 (ADAR1) WRITER View Details
Regulated Target hsa-mir-18a View Details
Crosstalk Relationship A-to-I  →  m6A Enhancement
Crosstalk Mechanism RNA modification indirectly impacts m6A modification through downstream signaling pathways
Crosstalk Summary ADAR1 interacts with hsa-mir-18a, increasing it's A-to-I level and promoting its physical interaction with Mutated in multiple advanced cancers 1 (PTEN), which was regulated by IGF2BP1-mediated m6A modification.
