m6A alters ribosome dynamics to initiate mRNA degradation
m6A is a potent inducer of ribosome stalling and collisions that trigger YTHDF-mediated
mRNA degradation, a process that highlights the ribosome as a critical sensor linking
translation dynamics to m6...

Structural basis for nucleolin recognition of MYC promoter G-quadruplex
The MYC oncogene promoter G-quadruplex (MycG4) regulates transcription and is a prevalent G4 locus in immortal cells. Nucleolin, a major MycG4-binding protein, exhibits greater affinity for MycG4 than...
