Interactioni

Subunit structurei

Septins polymerize into heterooligomeric protein complexes that form filaments, and associate with cellular membranes, actin filaments and microtubules. GTPase activity is required for filament formation. Filaments are assembled from asymmetrical heterotrimers, composed of SEPT2, SEPT6 and SEPT7 that associate head-to-head to form a hexameric unit. Within the trimer, directly interacts with SEPT6, while interaction with SEPT2 seems indirect. In the absence of SEPT6, forms homodimers. Interacts directly with CENPE and links CENPE to septin filaments composed of SEPT2, SEPT6 and SEPT7. Interacts with SEPT5 and SEPT8 By similarity. Interacts with SEPT9 and SEPT11.By similarity5 Publications
