Rab GDI: a solubilizing and recycling factor for rab9 protein.

abstract：:Programmed DNA rearrangements are important processes present in many organisms. In the ciliated protozoan Tetrahymena thermophila, DNA rearrangements occur during the sexual conjugation process and lead to the deletion of thousands of specific DNA segments and fragmentation of the chromosomes. In this study, we found...

abstract：:In Schizosaccharomyces pombe, cytokinesis requires the assembly and constriction of an actomyosin-based contractile ring (CR). A single essential formin, Cdc12, localizes to the cell middle upon mitotic onset and nucleates the F-actin of the CR. Cdc12 medial recruitment is mediated in part by its direct binding to the...
