{gene_symbol} (Septin {last_digit}) is a member of the septin family of GTP-binding proteins that play essential roles in cytoskeleton organization, cell division, and membrane dynamics. Septins are highly conserved GTPases that form hetero-oligomeric complexes and function as scaffolds and diffusion barriers in cellular compartments.
The septin family consists of 13 members in humans (SEPT1-SEPT12, SEPT14) that assemble into various higher-order structures including filaments, rings, and bundles. {gene_symbol} has been implicated in neurological disorders and neurodegenerative diseases.
SEPT2 (Septin 2) is a member of the septin family of GTP-binding proteins that play essential roles in cellular organization, cytokinesis, and cytoskeletal dynamics. SEPT2 is a core component of septin heterooligomeric filaments that function as scaffolds and diffusion barriers in eukaryotic cells. In the nervous system, septins are critically involved in synaptic function, neuronal migration, and dendritic spine morphogenesis.
Located on chromosome 2q37.3, SEPT2 is ubiquitously expressed with particularly high levels in the brain, where it localizes to synaptic terminals, dendritic spines, and the axon initial segment. Septin dysfunction has been implicated in neurodevelopmental disorders, neurodegenerative diseases, and various cancers.## Function
SEPT2 encodes septin 2, a member of the septin family of GTP-binding proteins. Septins form hetero-oligomeric complexes that function as scaffolds and barriers in cellular organization. SEPT2 is a core component of septin filaments and plays essential roles in cytokinesis, membrane trafficking, and cytoskeletal organization. In neurons, septins are involved in synaptic vesicle trafficking, axon guidance, and dendritic spine morphogenesis.
Widely expressed in most tissues, with high expression in brain. In the brain, SEPT2 is expressed in neurons throughout the cerebral cortex, hippocampus, and cerebellum. It localizes to synaptic terminals and dendritic spines.
