Effects of Bni5 Binding on Septin Filament Organization.
Septins are a protein family found in all eukaryotes (except higher plants) that have roles in membrane remodeling and formation of diffusion barriers and as a scaffold to recruit other proteins. In budding yeast, proper execution of cytokinesis and cell division requires the formation of a collar of circumferential filaments at the bud neck. These filaments are assembled from apolar septin het...
متن کاملSeptin filament organization in Saccharomyces cerevisiae
Septins are a family of GTP-binding, membrane-interacting cytoskeletal proteins, highly conserved and essential in all eukaryotes (with the exception of plants). Septins play important roles in a number of cellular events that involve membrane remodeling and compartmentalization. One such event is cytokinesis, the last stage of cell division. While cytokinesis is ultimately achieved via the mec...
متن کاملGTP Binding Induces Filament Assembly of a Recombinant Septin
The septins are a family of GTPases involved in cytokinesis in budding yeast, Drosophila, and vertebrates (see for review). Septins are associated with a system of 10 nm filaments at the S. cerevisiae bud neck, and heteromultimeric septin complexes have been isolated from cell extracts in a filamentous state. A number of septins have been shown to bind and hydrolyze guanine nucleotide. However,...
متن کاملProtein-protein interactions governing septin heteropentamer assembly and septin filament organization in Saccharomyces cerevisiae.
Mitotic yeast (Saccharomyces cerevisiae) cells express five related septins (Cdc3, Cdc10, Cdc11, Cdc12, and Shs1) that form a cortical filamentous collar at the mother-bud neck necessary for normal morphogenesis and cytokinesis. All five possess an N-terminal GTPase domain and, except for Cdc10, a C-terminal extension (CTE) containing a predicted coiled coil. Here, we show that the CTEs of Cdc3...
متن کاملEffects of crosslinks on motor-mediated filament organization
Crosslinks and molecular motors play an important role in the organization of cytoskeletal filament networks. Here we incorporate the effect of crosslinks into our model of polar motor-filament organization [Phys. Rev. E 71, 050901 (2005)], through suppressing the relative sliding of filaments in the course of motor-mediated alignment. We show that this modification leads to a nontrivial macros...
