Crosstalk ID
M6ACROT00435
[1], [2], [3], [4]
m6A modification NEAT1 NEAT1 METTL14 Methylation : m6A sites Indirect Inhibition RNA modification MIR125A MIR125A METTL1 Methylation : modification sites
m6A Modification:
m6A Regulator Methyltransferase-like 14 (METTL14) WRITER
m6A Target Nuclear paraspeckle assembly transcript 1 (NEAT1)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> N7-methylguanosine (m7G)
Epigenetic Regulator Methyltransferase-like protein 1 (METTL1) WRITER View Details
Regulated Target MicroRNA 125a (MIR125A) View Details
Crosstalk Relationship m6A  →  m7G Inhibition
Crosstalk Mechanism m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary METTL14 interacts with Nuclear paraspeckle assembly transcript 1 (NEAT1), increasing its m6A level and inhibiting its physical interaction with MicroRNA 125a (MIR125A), which was regulated by METTL1-mediated m7G modification.
