We created a high-throughput modality of photoactivated localization microscopy (PALM) that enables automated 3D PALM imaging of hundreds of synchronized bacteria during all stages of the cell cycle. We used high-throughput PALM to investigate the nanoscal ...
Mutations in the parkin gene cause early-onset, autosomal recessive Parkinson's disease. Parkin functions as an E3 ubiquitin ligase to mediate the covalent attachment of ubiquitin monomers or linked chains to protein substrates. Substrate ubiquitination ca ...
Several methods are available to manipulate bacterial chromosomes(1-3). Most of these protocols rely on the insertion of conditionally replicative plasmids (e.g. harboring pir-dependent or temperature-sensitive replicons(1,2)). These plasmids are integrate ...
Cytokinesis is the final stage of the cell cycle, and ensures completion of both genome segregation and organelle distribution to the daughter cells. Cytokinesis requires the cell to solve a spatial problem (to divide in the correct place, orthogonally to ...
Nucleosome depletion at transcription start sites (TSS) has been documented genome-wide in multiple eukaryotic organisms. However, the mechanisms that mediate this nucleosome depletion and its functional impact on transcription remain largely unknown. We h ...
During the division of a mother cell into two daughter cells the genetic material of the mother cell is replicated and segregated to the daughter cells before the cytoplasm divides into two portions in a process called cytokinesis. In order to maintain the ...
PfPK7 is an orphan protein kinase of Plasmodium falciparum with maximal homology to MEK3/6 and to fungal protein kinase A proteins in its C-terminal and N-terminal regions, respectively. We showed previously that recombinant PfPK7 is active on various subs ...
Identification of proteins in 3D maps of cells is a main challenge in structural cell biology. For light microscopy (LM) clonable reagents such as green fluorescent protein represented a real revolution and equivalent reagents for transmission electron mic ...
Over the last decade, several protein kinases inhibitors have reached the market for cancer chemotherapy. The kinomes of pathogens represent potentially attractive targets in infectious diseases. The functions of the majority of protein kinases of Plasmodi ...
A novel mutant screen in fission yeast has identified the 'ethanol dependent' protein etd1p as a potential link between the septation initiation network (SIN), which initiates cytokinesis, and the actomyosin contractile ring that drives separation of the t ...
