Crosstalk ID
M6ACROT00413
[1], [2], [3], [4], [5], [6], [7], [8]
RNA modification MIR21 MIR21 ADARB1 Methylation : modification sites Indirect Inhibition m6A modification PTEN PTEN METTL14 Methylation : m6A sites
m6A Modification:
m6A Regulator Methyltransferase-like 14 (METTL14) WRITER
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 21 (MIR21) 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 21 (MIR21), increasing it's A-to-I level and inhibiting its physical interaction with Mutated in multiple advanced cancers 1 (PTEN), which was regulated by METTL14-mediated m6A modification.
