Introducing WERAM: Find Integrated Info on Your Histone Regulator in Your Favorite Species

January 5, 2017 Blanca Valle

Recently Dr. Yu Xue’s group, at the Huazhong University of Science and Technology in Wuhan, China, developed a database designated as Eukaryotic Writers, Erasers and Readers protein of Histone Acetylation and Methylation system Database (WERAM). WERAM is a comprehensive database containing integrated information on the writers, erasers, and readers of histone acetylation and methylation. Namely writers are the enzymes that catalyze acetylation and methylation, the erasers are the enzymes that remove these marks, and the readers are proteins that recognize and interact [more…]

Introducing O-GlcNAc – The Latest Addition to the Orchestra of Epigenetic Modifications

December 15, 2014 Sam Keating

Post-translational modifications are well known for their influence on protein stability, enzymatic functions, as well as protein:protein interactions. At the level of gene expression, acetylation, methylation, phosphorylation, ADP-ribosylation, ubiquitination and SUMOylation are some of the most prevalent chemical modifications that regulate transcription factors and the chromatin template (the complex of DNA and histone proteins) alike. In particular, the manifold modifications occurring on the histone proteins that closely associate with DNA are proposed to constitute a gene-regulating code (the histone code). [more…]
