WebFig. 1 a) The DNA sequence of the probe/target pairs and methylation states used for protein assessment are shown with the methylated cytosine bases bolded and underlined. The sequence is from the MGMT gene and contains three CpG dinucleotides, one of which is methylated in the hemi-methylated and symmetrically methylated states used in this … Web28 jul. 2024 · Hahm et al. describe a regulatory mechanism of UHRF1 in DNA methylation maintenance. UHRF1 acetylation by PCAF at lysine 490 disrupts the binding affinity of UHRF1 to hemi-methylated DNA in nascent DNA. These findings suggest that fine-tuned acetylation of UHRF1 is essential for inheritance of epigenomic information.
