Tumor progression is a multistep process in which proproliferation mutations must be accompanied by suppression of senescence. In melanoma, proproliferative signals are provided by activating mutations in NRAS and BRAF, whereas senescence is bypassed by in ...
The mitogen-activated protein kinase (MAPK) cascades are ubiquitous in eukaryotic signal transduction, and these pathways are conserved in cells from yeast to mammals. They relay extracellular stimuli from the plasma membrane to targets in the cytoplasm an ...
Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotin ...
The fission yeast septation initiation network, or SIN, is a signal transduction network that is required for septum formation in Schizosaccharomyces pombe. Its activity is tightly regulated through the cell cycle, to ensure proper co-ordination of mitosis ...
Eukaryotic cells are organized into a complex system of subcompartments, each with its distinct protein and lipid composition. A continuous flux of membranes crosses these compartments, and in some cases direct connections exist between the different organ ...
The efficacy and success of many cellular processes is dependent on a tight orchestration of proteins trafficking to and from their site(s) of action in a time-controlled fashion. Recently, a dynamic cycle of palmitoylation/de-palmitoylation has been shown ...
In fission yeast, the onset of septation is signalled through the septum initiation network (SIN) signaling pathway. Similarly, in budding yeast the onset of budding is signalled through the mitotic exit network (MEN) pathway. We previously characterized i ...
The in vivo and in vitro labeling of fusion proteins with synthetic mols. capable of probing and controlling protein function has the potential to become an important method in functional genomics and proteomics. We have recently introduced an approach for ...
Point mutations in the kinase domain of BCR-ABL are the most common mechanism of drug resistance in chronic myeloid leukemia (CML) patients treated with ABL kinase inhibitors, including imatinib. It has also been shown in vitro that mutations outside the k ...
The identification of phosphorylation sites in proteins provides a powerful tool to study signal transduction pathways and to establish interaction networks involving signaling elements. Using different strategies to identify phosphorylated residues, we re ...
