.... The genetic interactions thus complement our protein interaction network and locate the polarity factors Boi1/2p and Bem1p at the center of a cortical sub-domain that organizes polar secretion and cooperates directly in vesicle tethering and docking. The network is held together by a system of SH3 domain...

... Signal transduction Cytoskeleton Yeast Protein interaction network The normal functioning of a cell requires constant interaction with its extracellular environment and with other cells, and these interactions lead to changes in cell physiology, cell shape and gene expression. Signals from...
