Experts in Septins

A family of GTP-binding proteins that were initially identified in YEASTS where they were shown to initiate the process of septation and bud formation. Septins form into hetero-oligomeric complexes that are comprised of several distinct septin subunits. These complexes can act as cytoskeletal elements that play important roles in CYTOKINESIS, cytoskeletal reorganization, BIOLOGICAL TRANSPORT, and membrane dynamics.
