Grouped By:  Matching UniProtKB accession

UniProtKB description:  Filament-forming GTP-binding protein. Lacks GTPase activity, which is likely due to absence of an essential threonine residue important for hydrolytic activity in septins. May be involved in membrane remodeling, potentially by its nucleotide-dependent cellular membrane association/dissociation ability (PubMed:24464615). Able to bind to phosphatidylinositol-4,5-bisphosphate (PIP2)-containing giant unilamellar vesicles (GUVs), which serve as a model of biological membranes. Self-assembles into ordered cage-like structures on the vesicle membrane. Binds also to 1,2-dioleoyl-sn-glycero-3-phospho-L-serine (DOPS)-containing vesicles suggesting the requirement for negatively charged membranes. Is also able to promote deformation of the GUVs (PubMed:27687162).
