Corralled by septin
License to glue eplication of DNA and cohesion of the resultant sister chromatids are two activities that must be coordinated. found that the same " licensing " process that gets DNA ready for replication is also necessary to allow loading of the cohesin complex responsible for sister chromatid cohesion. Gillespie and Hirano used the sequence of yeast cohesin-loading proteins to identify human ...
متن کاملHuman septin-septin interactions as a prerequisite for targeting septin complexes in the cytosol.
Septins are a cytosolic GTP-binding protein family first characterized in yeast, but gaining increasing recognition as critical protagonists in higher eukaryotic cellular events. Mammalian septins have been associated with cytokinesis and exocytosis, along with contributing to the development of neurological disorders. Ten different septins, divided into four groups, have been identified in mam...
متن کاملRole of nucleotide binding in septin-septin interactions and septin localization in Saccharomyces cerevisiae.
Septins are a conserved family of eukaryotic GTP-binding, filament-forming proteins. In Saccharomyces cerevisiae, five septins (Cdc3p, Cdc10p, Cdc11p, Cdc12p, and Shs1p) form a complex and colocalize to the incipient bud site and as a collar of filaments at the neck of budded cells. Septins serve as a scaffold to localize septin-associated proteins involved in diverse processes and as a barrier...
متن کاملMicroscopic simulation of membrane molecule diffusion on corralled membrane surfaces.
The current understanding of how receptors diffuse and cluster in the plasma membrane is limited. Data from single-particle tracking and laser tweezer experiments have suggested that membrane molecule diffusion is affected by the presence of barriers dividing the membrane into corrals. Here, we have developed a stochastic spatial model to simulate the effect of corrals on the diffusion of molec...
متن کاملPolarization of the Endoplasmic Reticulum by ER-Septin Tethering
Polarization of the plasma membrane (PM) into domains is an important mechanism to compartmentalize cellular activities and to establish cell polarity. Polarization requires formation of diffusion barriers that prevent mixing of proteins between domains. Recent studies have uncovered that the endoplasmic reticulum (ER) of budding yeast and neurons is polarized by diffusion barriers, which in ne...
