... in meiotic prophase. We discuss how dynein targets sites where it can exert a pulling force on the microtubule to transport cargo inside the cell. 1 Correspondence may be addressed to either author (email npavin@phy.hr or tolic@mpi-cbg.de ). A direct way to experimentally identify these steps...

... Arf GEFs and GAPs that have been identified, in the cell the different Arfs, GEFs and GAPs are targeted to specific compartments where they carry out their functions. We have embarked on studies to define regions of the Arf1 and Arf6 proteins that determine their sites of action and specific...

... to act as mitochondria-targeting vectors by testing whether they were internalized by isolated mitochondria, and by mitochondria within cells in culture. We also tested peptides conjugated to the mitochondria-targeting moiety triphenylphosphonium. We found no evidence for mitochondrial uptake...
