Actin mesh hinders microtubules
JCB • VOLUME 179 • NUMBER 4 • 2007 570 Actin mesh hinders microtubules L ike an iron curtain, a mesh of actin keeps microtubules in place in the fl y oocyte, according to Katja Dahlgaard, Daniel St Johnston, and colleagues (University of Cambridge, UK). When the mesh comes down, microtubules are washed into a new orientation by free-fl owing cytoplasm. Microtubule orientation in the fl y oocyte...
متن کاملArg links actin and microtubules
An anchor for motoring oxoplasma gondii , a parasite that can cause blindness and brain damage in immunocompromised individuals, spreads around the body and penetrates into cells using a bizarre spinning and corkscrewing motility. This motility is not dependent on any easily visible structure, such as a flagellum or lamellipodia, and the cell moves without changing shape. Now, Gaskins et al. (p...
متن کاملOrganelle Movements along Actin Filaments and Microtubules.
Organelle movements involving microtubules and actin filaments are a conspicuous and important feature of many plant cells. Movements have recently been supported in preparations of demembranated cytoplasm and reconstituted from purified proteins. The favored mechanism involves organelles carrying a force-generating ATPase moving along a track provided by either actin filaments or microtubules....
متن کاملCompare and contrast actin filaments and microtubules.
Many reviews have been written on the biochemistry and cell biology of actin filaments and microtubules individually (see Korn, 1982; Kirschner and Mitchison, 1986; Pollard, 1986a; Pollard and Cooper, 1986; Gelfand and Bershadsky, 1991; Caplow, 1992). Most labs work on one polymer or the other, which has led to something of a gulf between the actin and microtubule research fields. As a broad (a...
متن کاملInteraction of actin filaments with microtubules
Several cytological observations support the idea that actin filaments interact with microtubules, but the strongest evidence comes from biochemical experiments. The cytological observations include the colocalization of microtubules and actin in the mitotic spindle of dividing cells by electron microscopy (1-3) and light microscopy with fluorescent probes for actin (4-6) . There is, however, d...
