𝐍𝐞𝐰 𝐦𝐞𝐜𝐡𝐚𝐧𝐢𝐬𝐭𝐢𝐜 𝐢𝐧𝐬𝐢𝐠𝐡𝐭𝐬 𝐢𝐧𝐭𝐨 𝐭𝐡𝐞 𝐫𝐞𝐠𝐮𝐥𝐚𝐭𝐢𝐨𝐧 𝐨𝐟 𝐡𝐢𝐬𝐭𝐨𝐧𝐞 𝐬𝐮𝐩𝐩𝐥𝐲! Excited to share our latest collaboration led by tkjeong.bsky.social and ciaranfrater.bsky.social! Structural determination of the histone chaperone ASF1 and its regulator CODANIN-1 uncovers how CODANIN-1 counters ASF1 activity. 🧵👇
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
