Human 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 کاملGenetic interactions among regulators of septin organization.
Septins form a cortical scaffold at the yeast mother-bud neck that restricts the diffusion of cortical proteins between the mother and bud and serves as a signaling center that is important for governing various cell functions. After cell cycle commitment in late G(1), septins are assembled into a narrow ring at the future bud site, which spreads to form a mature septin hourglass immediately af...
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 کاملThe Mammalian Septin Interactome
Septins are GTP-binding and membrane-interacting proteins with a highly conserved domain structure involved in various cellular processes, including cytoskeleton organization, cytokinesis, and membrane dynamics. To date, 13 different septin genes have been identified in mammals (SEPT1 to SEPT12 and SEPT14), which can be classified into four distinct subgroups based on the sequence homology of t...
