Inhibition of DNMT1 methyltransferase activity via glucose-regulated O-GlcNAcylation alters the epigenome

S Heon, A Leung, KR Costello, S Parijat, K Hiroyuki… - eLife, 2023 - search.proquest.com
The DNA methyltransferase activity of DNMT1 is vital for genomic maintenance of DNA
methylation. We report here that DNMT1 function is regulated by O-GlcNAcylation, a protein …

Glucose-regulated O-GlcNAcylation of DNMT1 inhibits DNA methyltransferase activity and maintenance of genomic methylation

H Shin, A Leung, KR Costello, P Senapati, H Kato… - bioRxiv, 2022 - biorxiv.org
The production of O-GlcNAc for protein O-GlcNAcylation is highly tuned to the metabolic
state of the cell and thus can serve as a nutrient sensor responding to changes in metabolic …
