Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00144
[1], [2]
m6A modification ADARB1 ADARB1 METTL3 Methylation : m6A sites Direct Enhancement RNA modification HNRNPLL HNRNPLL ADARB1 Methylation : modification sites
m6A Modification:
m6A Regulator Methyltransferase-like 3 (METTL3) WRITER
m6A Target Double-stranded RNA-specific editase 1 (ADARB1)
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 Heterogeneous nuclear ribonucleoprotein L like (HNRNPLL) View Details
Crosstalk Relationship m6A  →  A-to-I Enhancement
Crosstalk Mechanism m6A modification directly impacts RNA modification through modulating the expression level of RNA modification regulator
Crosstalk Summary METTL3 methylates Double-stranded RNA-specific editase 1 (ADARB1) mRNA, thereby enhancing its protein expression, which subsequently promotes ADARB1 mediated A-to-I RNA editing of the Heterogeneous nuclear ribonucleoprotein L like (HNRNPLL) transcript.
