CC   -!- FUNCTION: Filament-forming cytoskeletal GTPase (By similarity). May
CC       play a role in platelet secretion (By similarity). Seems to participate
CC       in the process of SNARE complex formation in synaptic vesicles (By
CC       similarity). {ECO:0000250|UniProtKB:B0BNF1,
CC       ECO:0000250|UniProtKB:Q92599}.
CC   -!- SUBUNIT: Septins polymerize into heterooligomeric protein complexes
CC       that form filaments, and can associate with cellular membranes, actin
CC       filaments and microtubules. GTPase activity is required for filament
CC       formation (By similarity). Interacts with CDK14, SEPTIN4, SEPTIN5 and
CC       SEPTIN7 (By similarity). Interacts with VAMP2; the interaction inhibits
CC       interaction of VAMP2 with SYP (By similarity). Interacts with STX1A (By
CC       similarity). {ECO:0000250|UniProtKB:B0BNF1,
CC       ECO:0000250|UniProtKB:Q8CHH9, ECO:0000250|UniProtKB:Q92599}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:B0BNF1}.
CC       Cytoplasm, cytoskeleton {ECO:0000250}. Synapse
CC       {ECO:0000250|UniProtKB:B0BNF1}. Cell projection, axon
CC       {ECO:0000250|UniProtKB:B0BNF1}. Cytoplasmic vesicle, secretory vesicle,
CC       synaptic vesicle membrane {ECO:0000250|UniProtKB:B0BNF1}. Presynapse
CC       {ECO:0000250|UniProtKB:B0BNF1}. Note=Expressed in axons of immature
CC       neurons, localizes to synapses in mature neurons.
CC       {ECO:0000250|UniProtKB:B0BNF1}.
CC   -!- SIMILARITY: Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like
CC       GTPase superfamily. Septin GTPase family. {ECO:0000255|PROSITE-
CC       ProRule:PRU01056}.
