蛋白介绍
Multidomain protein that acts as a key epigenetic regulator by bridging DNA methylation and chromatin modification. Specifically recognizes and binds hemimethylated DNA at replication forks via its YDG domain and recruits DNMT1 methyltransferase to ensure faithful propagation of the DNA methylation patterns through DNA replication. In addition to its role in maintenance of DNA methylation, also plays a key role in chromatin modification: through its tudor-like regions and PHD- type zinc fingers, specifically recognizes and binds histone H3 trimethylated at 'Lys-9' (H3K9me3) and unmethylated at 'Arg-2' (H3R2me0), respectively, and recruits chromatin proteins. Enriched in pericentric heterochromatin where it recruits different chromatin modifiers required for this chromatin replication. Also localizes to euchromatic regions where it negatively regulates transcription possibly by impacting DNA methylation and histone modifications. Has E3 ubiquitin-protein ligase activity by mediating the ubiquitination of target proteins such as histone H3 and PML. It is still unclear how E3 ubiquitin-protein ligase activity is related to its role in chromatin in vivo. May be involved in DNA repair.

文献和实验Uhrf1 通过 Akt-mTOR 途径调控 iNKT 细胞的生存和分化
Uhrf1(或者被称为 Np95)是一个 DNA 甲基化和组蛋白泛素化的调控因子,在胚胎发育(embryogenesis)以及肿瘤发生(tumorigenesis)过程中有着重要作用。近日,上海中科院生化细胞所刘小龙课题组联合上海科技大学以及中国科学与技术大学在国际权威期刊 Cell 子刊 Cell Reports 上发表题为 Uhrf1 Controls iNKT Cell Survival and Differentiation through the Akt-mTOR Axis
10.21 华中科技大学 Nature 子刊揭示精母细胞中逆转录转座子沉默的分子机制
① 华中科技大学 Nature 子刊揭示精母细胞中逆转录转座子沉默的分子机制哺乳动物转座子(TEs)是一类可以在基因组自主移动的 DNA 片段,在短期内,TEs 激活也可威胁基因组完整性,进而导致肿瘤发生、病理性发育以及不育的发生。因此研究雄性生殖细胞中转座子的沉默机制对治疗男性不育有重要的临床价值。来自华中科技大学同济医学院生殖健康研究所袁水桥教授利用条件性基因敲除策略,在小鼠生殖细胞中特异性的敲除了 Uhrf1 基因,发现敲除小鼠完全不育,睾丸显著性变小,附睾中完全没有精子。进一步表型
