Background: In animal cells, cytokinesis begins shortly after the sister chromatids move to the spindle poles. The inner centromere protein (Incenp)has been implicated in both chromosome segregation and cytokinesis, but it is not known exactly how it mediates these two distinct processes.Results: We identified two Caenorhabditis elegans proteins, ICP-1 and ICP-2, with significant homology in their...
Background: During cytokinesis, the plasma membrane of the parent cell is resolved into the two plasma membranes of the daughter cells. Membrane fusion events mediated by the machinery that participates in intracellular vesicle trafficking might contribute to this process. Two classes of molecules that are required for membrane fusion are the t-SNAREs and the v-SNAREs. The t-SNAREs (syntaxins) comprise...
