Distribution of tubulin and actin through the cell division cycle of the fission yeast Schizosaccharomyces japonicus var. versatilis: a comparison with Schizosaccharomyces pombe.
Changes in the distribution of microtubules and F-actin through the cell division cycle of the fission yeast Schizosaccharomyces japonicus var. versatilis were investigated by fluorescence microscopy. The fluorescence images obtained with S. japonicus were markedly superior to those previously reported for S. pombe and revealed new details of cytoskeletal organization in this important genus. A...
متن کاملF-actin ring formation and the role of F-actin cables in the fission yeast Schizosaccharomyces pombe.
Cells of the fission yeast Schizosaccharomyces pombe divide by the contraction of the F-actin ring formed at the medial region of the cell. We investigated the process of F-actin ring formation in detail using optical sectioning and three-dimensional reconstruction fluorescence microscopy. In wild-type cells, formation of an aster-like structure composed of F-actin cables and accumulation of F-...
متن کاملNanoscale architecture of the Schizosaccharomyces pombe contractile ring
The contractile ring is a complex molecular apparatus which physically divides many eukaryotic cells. Despite knowledge of its protein composition, the molecular architecture of the ring is not known. Here we have applied super-resolution microscopy and FRET to determine the nanoscale spatial organization of Schizosaccharomyces pombe contractile ring components relative to the plasma membrane. ...
متن کاملThe PCH family protein, Cdc15p, recruits two F-actin nucleation pathways to coordinate cytokinetic actin ring formation in Schizosaccharomyces pombe
Cytokinetic actin ring (CAR) formation in Schizosaccharomyces pombe requires two independent actin nucleation pathways, one dependent on the Arp2/3 complex and another involving the formin Cdc12p. Here we investigate the role of the S. pombe Cdc15 homology family protein, Cdc15p, in CAR assembly and find that it interacts with proteins from both of these nucleation pathways. Cdc15p binds direct...
متن کاملActin in dividing cells: contractile ring filaments bind heavy meromyosin.
Many microfilaments and microtubules are well preserved after glycerol-extraction of HeLa cells at room temperature (22 degrees ). Incubation in heavy meromyosin from rabbit skeletal muscle results in conspicuous and characteristic "decoration" of microfilaments of the contractile ring. Decoration is completely prevented by 10 mM ATP or 2 mM pyrophosphate, and fails to occur if heavy meromyosin...
