متن کاملCell polarity: Fixing cell polarity with Pins
A protein complex is assembled in a step-wise manner at the apical pole of Drosophila neuroblasts. This complex organizes the apical-basal polarity of asymmetrically dividing neuroblasts, and may act via G-protein signalling.
متن کاملCell polarity
The Minisymposium on Cell Polarity featured a broad array of systems. The session began with talks on asymmetric cortical polarity cues. Lesilee Rose (University of California, Davis) discussed asym-metric division in Caenorhabditis elegans. In the one-cell embryo, PAR polarity proteins regulate cytoplasmic polarity and cortical forces that position the spindle. The latter require the DEP domai...
متن کاملThe cell biology of planar cell polarity
Planar cell polarity (PCP) refers to the coordinated alignment of cell polarity across the tissue plane. Key to the establishment of PCP is asymmetric partitioning of cortical PCP components and intercellular communication to coordinate polarity between neighboring cells. Recent progress has been made toward understanding how protein transport, endocytosis, and intercellular interactions contri...
متن کاملCell Polarity: Lateral Perspectives
The outer and inner (lateral) plasma membranes of the outermost cell layer in plants provide selective barriers to the environment. Recent studies provide perspectives on how asymmetric protein localization is established at lateral membranes.
