ID:SEPT9_MOUSE DESCRIPTION: RecName: Full=Septin-9; AltName: Full=SL3-3 integration site 1 protein; FUNCTION: Filament-forming cytoskeletal GTPase (By similarity). May play a role in cytokinesis (Potential). SUBUNIT: Septins polymerize into heterooligomeric protein complexes that form filaments, and associate with cellular membranes, actin filaments, and microtubules. GTPase activity is required for filament formation. Interacts with SEPT2, SEPT6, SEPT7, SEPT11 and SEPT14. Interacts with RTKN and ARHGEF18 (By similarity). SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton. Note=In an epithelial cell line, concentrates at cell-cell contact areas. After TGF-beta1 treatment and induction of epithelial to mesenchymal transition, colocalizes with actin stress fibers. TISSUE SPECIFICITY: Expressed in all tissues examined except muscle. Isoforms are differentially expressed in testes, kidney, liver, heart, spleen and brain. DEVELOPMENTAL STAGE: At 8 dpc mainly expressed in the lateral plate mesoderm and the somites. Beginning at 9 dpc the lateral plate expression is clearly focused in the developing fore- and hindlimb buds. In the cephalic region, expressed in the first and second branchial arch, in the nasal process and around the otic pit. At 9.5 dpc strongest expression is observed in the mesenchyme of the branchial arches, the limbs, and the developing dorsal root ganglia. Weak to intermediate expression is found in the neural epithelium. Expression is seen in the newly formed somites in the tail bud of older embryos. During formation of the digits, expression seems to outline the surviving tissue bordering it towards the apoptotic webbing. Expression is seen in the developing outer ear and in several areas known to be regulated by intensive epithelial mesenchymal interactions, like the viscera follicles and the developing mammary glands. DISEASE: Note=Putative proto-oncogene involved in T-cell lymphomagenesis. May play a role in leukemogenesis. MISCELLANEOUS: Targeted by proviral insertion in T-cell lymphomas induced by the murine retrovirus SL3-3 MuLV. SIMILARITY: Belongs to the septin family. SEQUENCE CAUTION: Sequence=BAC65697.2; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.
ModBase Predicted Comparative 3D Structure on Q80UG5
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
