Prenylated chalcone xanthohumol associates with histones in breast cancer cells: a novel target identified by a monoclonal antibody Ghent University
Extracting histones for the specific purpose of label-free MS Ghent University
Cell cycle-dependent O-GlcNAc modification of tobacco histones and their interaction with the tobacco lectin University of Antwerp
The Nicotiana tabacum agglutinin or Nictaba is a nucleocytoplasmic lectin that is expressed in tobacco after the plants have been exposed to jasmonate treatment or insect herbivory. Nictaba specifically recognizes GlcNAc residues. Recently, it was shown that Nictaba is interacting in vitro with the core histone proteins from calf thymus. Assuming that plant histones similar to their animal counterparts undergo O-GlcNAcylation, this interaction ...
Structural plasticity of histones H3-H4 facilitates their allosteric exchange between RbAp48 and ASF1 University of Antwerp
The mechanisms by which histones are disassembled and reassembled into nucleosomes and chromatin structure during DNA replication, repair and transcription are poorly understood. A better understanding of the processes involved is, however, crucial if we are to understand whether and how histone variants and post-translationally modified histones are inherited in an epigenetic manner. To this end we have studied the interaction of the histone ...
Progressive methylation of ageing histones by Dot1 functions as a timer University of Antwerp
Post-translational modifications of histone proteins have a crucial role in regulating gene expression. If efficiently re-established after chromosome duplication, histone modifications could help propagate gene expression patterns in dividing cells by epigenetic mechanisms. We used an integrated approach to investigate the dynamics of the conserved methylation of histone H3 Lys 79 (H3K79) by Dot1. Our results show that methylation of H3K79 ...
The human N-alpha-acetyltransferase 40 (hNaa40p/hNatD) is conserved from yeast and N-terminally acetylates histones H2A and H4 Ghent University
Histone clipping : the punctuation in the histone code Ghent University
Histone clipping was first discovered in the 1960s and still is a lingering mystery. Considering the essential roles of histones in regulating eukaryotic transcription through the histone code, clipping is a post-translational modification that appeals to the imagination. In this issue of EMBO Reports, Marruecos and colleagues investigate histone H4 clipping during intestinal development (Marruecos et al, 2021), and are providing crucial clues ...
Statins and histone deacetylase inhibitors affect lamin A/C histone deacetylase 2 interaction in human cells University of Antwerp
We recently identified lamin A/C as a docking molecule for human histone deacetylase 2 (HDAC2) and showed involvement of HDAC2-lamin A/C complexes in the DNA damage response. We further showed that lamin A/C-HDAC2 interaction is altered in Hutchinson-Gilford Progeria syndrome and other progeroid laminopathies. Here, we show that both inhibitors of lamin A maturation and small molecules inhibiting HDAC activity affect lamin A/C interaction with ...
