A plasma membrane-enriched fraction has been isolated from corn leaf mesophyll protoplasts and its identity confirmed with the aid of an external label, diazotized [(125)I]iodosulfanilic acid. Gentle cell disruption enabled internal organelles to be maintained intact and thus facilitated separation from the plasma membrane. The plasma membrane-enriched fraction was devoid of chloroplast or mito...
Cell migration and invasion require increased plasma membrane dynamics and ability to navigate through dense stroma, thereby exposing plasma membrane to tremendous physical stress. Yet, it is largely unknown how metastatic cancer cells acquire an ability to cope with such stress. Here we show that S100A11, a calcium-binding protein upregulated in a variety of metastatic cancers, is essential fo...
Plasma membrane repair in animal cells uses synaptotagmin 7, a Ca(2+)-activated membrane fusion protein that mediates delivery of intracellular membranes to wound sites by a mechanism resembling neuronal Ca(2+)-regulated exocytosis. Here, we show that loss of function of the homologous Arabidopsis thaliana Synaptotagmin 1 protein (SYT1) reduces the viability of cells as a consequence of a decre...
