CC -!- FUNCTION: Filament-forming cytoskeletal GTPase. Required for normal
CC organization of the actin cytoskeleton. Required for normal progress
CC through mitosis. Involved in cytokinesis. Required for normal
CC association of CENPE with the kinetochore. Plays a role in ciliogenesis
CC and collective cell movements. Forms a filamentous structure with
CC SEPTIN12, SEPTIN6, SEPTIN2 and probably SEPTIN4 at the sperm annulus
CC which is required for the structural integrity and motility of the
CC sperm tail during postmeiotic differentiation (By similarity).
CC {ECO:0000250, ECO:0000250|UniProtKB:Q16181}.
CC -!- SUBUNIT: Septins polymerize into heterooligomeric protein complexes
CC that form filaments, and associate with cellular membranes, actin
CC filaments and microtubules. GTPase activity is required for filament
CC formation. Filaments are assembled from asymmetrical heterotrimers,
CC composed of SEPTIN2, SEPTIN6 and SEPTIN7 that associate head-to-head to
CC form a hexameric unit. Within the trimer, directly interacts with
CC SEPTIN6, while interaction with SEPTIN2 seems indirect. In the absence
CC of SEPTIN6, forms homodimers. Interacts directly with CENPE and links
CC CENPE to septin filaments composed of SEPTIN2, SEPTIN6 and SEPTIN7.
CC Interacts with SEPTIN5, SEPTIN8, SEPTIN9 and SEPTIN11. Component of a
CC septin core octomeric complex consisting of SEPTIN12, SEPTIN7, SEPTIN6
CC and SEPTIN2 or SEPTIN4 in the order 12-7-6-2-2-6-7-12 or 12-7-6-4-4-6-
CC 7-12 and located in the sperm annulus; the SEPTIN12:SEPTIN7 association
CC is mediated by the respective GTP-binding domains (By similarity).
CC {ECO:0000250, ECO:0000250|UniProtKB:Q16181}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm. Chromosome, centromere, kinetochore
CC {ECO:0000250}. Cytoplasm, cytoskeleton, spindle {ECO:0000250}. Cleavage
CC furrow {ECO:0000250}. Midbody {ECO:0000250}. Cytoplasm, cytoskeleton,
CC cilium axoneme {ECO:0000250}. Cell projection, cilium, flagellum
CC {ECO:0000250|UniProtKB:Q16181}. Note=Distributed throughout the
CC cytoplasm in prometaphase cells. Associated with the spindle during
CC metaphase. Associated with the central spindle and at the cleavage
CC furrow in anaphase cells. Detected at the midbody in telophase. Found
CC in the sperm annulus (By similarity). Associated with actin stress
CC fibers (By similarity). {ECO:0000250, ECO:0000250|UniProtKB:Q16181}.
