Repair of DNA double-strand breaks leaves heritable impairment to genome function
Upon DNA breakage, a genomic locus undergoes alterations in three-dimensional chromatin architecture to facilitate signaling and repair. Although cells possess mechanisms to repair damaged DNA, it is ...

CODANIN-1 sequesters ASF1 by using a histone H3 mimic helix to regulate the histone supply
Nature Communications - CODANIN-1 negatively regulates the function of ASF1, the key chaperone for histone H3-H4 supply. Here the authors present the cryo-EM structure of the CODANIN-1_ASF1A...

Excited to share the first of 2 new papers diving into functions of UHRF1 ubiquitin ligase activity. Here, a connection to the support of 5mC maintenance in regions of low CpG density. These same regions are prone to 5mC loss in cancer. A potential mechanistic link to PMD formation. #epigenetics

UHRF1 ubiquitin ligase activity supports the maintenance of low-density CpG methylation
Abstract. The RING E3 ubiquitin ligase UHRF1 is an established cofactor for DNA methylation inheritance. The model posits that nucleosomal engagement throu
