Cytokinesis.
The actomyosin contractile-ring mechanism remains the paradigm for cytokinesis after 20 years of experimental testing. Recent evidence suggests that Ca2+ triggers the contraction and that cell-cycle kinases regulate the timing of cytokinesis. New work is required to identify the signals from the mitotic spindle that specify the position of the furrow.
