Crosstalk ID
M6ACROT00624
[1], [2], [3]
RNA modification NEAT1 NEAT1 ADAR Methylation : modification sites Indirect Enhancement m6A modification MIR126 MIR126 METTL14 Methylation : m6A sites
m6A Modification:
m6A Regulator Methyltransferase-like 14 (METTL14) WRITER
m6A Target microRNA 126 (MIR126)
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 Nuclear paraspeckle assembly transcript 1 (NEAT1) 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 Nuclear paraspeckle assembly transcript 1 (NEAT1), increasing it's A-to-I level and promoting its physical interaction with microRNA 126 (MIR126), which was regulated by METTL14-mediated m6A modification.
