Mitochondria help dynamins get a grip
T he dynamin-like GTPases spur mitochondria to break up. Two papers (1, 2) reveal new details about the molecular platforms that position these mitochondria-splitting proteins on the organelles. In yeast, the dynamin-like GTPase Dnm1 dismembers mitochondria by settling on the outer surface of the mitochondrial membrane and polymerizing into spirals that cleave the organelle (3). Two other prote...
متن کاملMicrotubule Dynamics: Kinetochores get a grip
Analysis of the interactions between purified motor proteins or isolated chromosomes and shrinking microtubules has shed light on the mechanism of chromosome segregation at mitosis.
متن کاملMembrane Traffic: Arl GTPases Get a GRIP on the Golgi
A subset of the golgin family of large coiled-coil proteins have a GRIP domain that mediates their localization to the trans-Golgi. Two recent papers show that the Arl3p and Arl1p small GTPases act sequentially to recruit GRIP domain proteins to the Golgi.

better response rates. Marti cautioned that "fludarabine is not an ideal drug however, as prolonged administration of the drug results in severe T-cell depletion and suppression." Many leukemia researchers think 506U may be the drug of choice for treating CLL in the next decade. In Phase I trials it has shown greater efficacy than any other drug commercially available. It will be entering phase...
متن کاملNa+ channels get anchored…with a little help
Neurons have high densities of voltage-gated Na(+) channels that are restricted to axon initial segments and nodes of Ranvier, where they are responsible for initiating and propagating action potentials. New findings (Bréchet, A., M.-P. Fache, A. Brachet, G. Ferracci, A. Baude, M. Irondelle, S. Pereira, C. Leterrier, and B. Dargent. 2008. J. Cell Biol. 183:1101-1114) reveal that phosphorylation...
