Septins

WebSeptins are a family of GTP-binding proteins that associate with cellular membranes and the cytoskeleton. Their ability to polymerize into filamentous structures permits them to serve as diffusion barriers for membrane proteins and as multi-molecular scaffolds that recruit components of signaling pathways. At the cellular level, septins contribute to the … WebSeptins are conserved cytoskeletal GTP-binding proteins identified in almost all eukaryotes except higher plants. Mammalian septins comprise 13 family members with either …

WebSeptins are involved in a process called cytokinesis, which is the step in cell division when the fluid inside the cell (cytoplasm) divides to form two separate cells. The septin-9 protein also seems to act as a tumor suppressor, which means that it regulates cell growth and keeps cells from dividing too fast or in an uncontrolled way. WebApr 13, 2024 · Septins are an evolutionarily conserved family of GTP-binding proteins that interact with cellular membranes to form nonpolar filaments and higher-order ring-like structures (Spiliotis and McMurray, 2024; Woods and Gladfelter, 2024).Septin interactions with the plasma membrane underpin a variety of eukaryotic cell hallmarks, including the … WebFirst, a and/or septins in order to locally anchor the contractile ring reduction in the amount of E-cadherin could be linked to the supply (Goldbach et al., 2010).
