m6A-centered Crosstalk Information

Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation

m6A Modification:
Crosstalk ID	M6ACROT00421				[1], [2], [3], [4], [5]
m⁶A modification XIST XIST METTL3 Methylation : m⁶A sites Indirect Enhancement RNA modification MIR21 MIR21 ADARB1 Methylation : modification sites
m6A Regulator	Methyltransferase-like 3 (METTL3)			WRITER	Regulator Info
m6A Target	X inactive specific transcript (XIST)				Targert Gene
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	m6A → A-to-I			Enhancement
Crosstalk Mechanism	m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary	METTL3 interacts with X inactive specific transcript (XIST), increasing its m6A level and promoting its physical interaction with MicroRNA 21 (MIR21), which was regulated by ADARB1-mediated A-to-I modification.
