m6A-centered Crosstalk Information

Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation

m6A Modification:
Crosstalk ID	M6ACROT00174				[1], [2], [3]
m⁶A modification ADAR1 ADAR1 METTL3 Methylation : m⁶A sites Direct Enhancement RNA modification MIR18A MIR18A ADAR Methylation : modification sites
m6A Regulator	Methyltransferase-like 3 (METTL3)			WRITER	Regulator Info
m6A Target	Interferon-inducible protein 4 (ADAR1)				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	Interferon-inducible protein 4 (ADAR1)			WRITER	View Details
Regulated Target	hsa-mir-18a				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 Interferon-inducible protein 4 (ADAR1) mRNA, thereby enhancing its protein expression, which subsequently promotes ADAR mediated A-to-I RNA editing of the hsa-mir-18a transcript.
