Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00652
[1], [2], [3], [4]
m6A modification MIR106B MIR106B HNRNPA2B1 : m6A sites Indirect Enhancement RNA modification PTEN PTEN TET1 Demethylation : modification sites
m6A Modification:
m6A Regulator Heterogeneous nuclear ribonucleoproteins A2/B1 (HNRNPA2B1) READER
m6A Target hsa-mir-106b
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> 5-methylcytidine (m5C)
Epigenetic Regulator Methylcytosine dioxygenase TET1 (TET1) ERASER View Details
Regulated Target Mutated in multiple advanced cancers 1 (PTEN) View Details
Crosstalk Relationship m6A  →  m5C Enhancement
Crosstalk Mechanism m6A modification indirectly impacts RNA modification through downstream signaling pathways
Crosstalk Summary HNRNPA2B1 interacts with hsa-mir-106b, decreasing its m6A level and promoting its physical interaction with Mutated in multiple advanced cancers 1 (PTEN), which was regulated by TET1-mediated m5C modification.
