BACKGROUND Polarised trafficking of proteins is critical for normal expression of the epithelial phenotype, but its genetic control is not understood. The regulatory gene lin-26 is essential for normal epithelial differentiation in the nematode Caenorhabditis elegans. To identify potential effectors of lin-26, we characterised mutations that result in(More)
Clathrin provides an external scaffold to form small 50-100-nm transport vesicles. In contrast, formation of much larger dense-cored secretory granules is driven by selective aggregation of internal cargo at the trans-Golgi network; the only known role of clathrin in dense-cored secretory granules formation is to remove missorted proteins by small, coated(More)

The rapid exocytosis of von Willebrand factor (VWF) in response to vascular injury can be attributed to the fact that VWF is stored in the Weibel-Palade bodies (WPBs) of endothelial cells. We describe a system for examining the ability of VWF to drive both the formation of a storage compartment and the function of that compartment with respect to regulated(More)
We present gene prioritization system (GPSy), a cross-species gene prioritization system that facilitates the arduous but critical task of prioritizing genes for follow-up functional analyses. GPSy's modular design with regard to species, data sets and scoring strategies enables users to formulate queries in a highly flexible manner. Currently, the system(More)
During asymmetric cell division, the mitotic spindle and polarized myosin can both determine the position of the cytokinetic furrow. However, how cells coordinate signals from the spindle and myosin to ensure that cleavage occurs through the spindle midzone is unknown. Here, we identify a novel pathway that is essential to inhibit myosin and coordinate(More)
