In order to correlate the molecular characteristics of these proteins with their function, we have analyzed the molecules in detail and studied at the ultrastructural level the condensation of chromatin during the spermiogenesis in both species. D. labrax has a true protamine of 34 amino acid ...
Non-histone proteins were extracted from chromatin of citric acid-isolated, and NPT-isolated (cemulsol-12) salivary gland nuclei and citric acid-isolated midgut nuclei of Drosophila hydei. The migration pattern on sodium dodecyl sulphate-urea polyacrylamide gels of the two types of salivary gland ...
Pioneer transcription factors direct cell differentiation by deploying new enhancer repertoires through their unique ability to target and initiate remodelling of closed chromatin. The initial steps of their action remain undefined, although pioneers hav
However, such an increase in Mek phosphorylation when the MAPK pathway is inhibited has been observed previously (Fritsche-Guenther et al., 2011, Sturm et al., 2010) and is due to a reduction of negative feedback regulation, such that proteins that are upstream in the cascade are ...
Of these xDNMT1-interacting chromatin proteins, 24 were highly enriched in the xDNMT1 pull-downs in response to the addition of ubiquitin to UbVS-treated extracts (log2fold-change >2, p value < 0.05; Fig. 1a, Supplementary Data 1). We also found an enrichment of eight ubiquitylated and...
Analysis of interphase node proteins in fission yeast by quantitative and super resolution fluorescence microscopy FPALM superresolution microscopy and quantitative confocal microscopy reveal that interphase nodes, the precursors to the fission yeast cytokinetic contractile ring, are discrete unitary structures...
Dynamic genome architecture in the nuclear space: regulation of gene expression in three dimensions The regulation of gene expression is mediated by interactions between chromatin and protein complexes. The importance of where and when these interactions ... Christian Lanctt,T Cheutin,M Cremer,... ...

We also found that, despite their strong impact on centromere distribution, condensin II and CRWN proteins have little effect on chromatin organization involved in the control of gene expression, indicating a robustness of chromatin organization regardless of the type of centromere distribution. This ...
