ID:SEPT4_HUMAN DESCRIPTION: RecName: Full=Septin-4; AltName: Full=Apoptosis-related protein in the TGF-beta signaling pathway; Short=ARTS; AltName: Full=Bradeion beta; AltName: Full=Brain protein H5; AltName: Full=CE5B3 beta; AltName: Full=Cell division control-related protein 2; Short=hCDCREL-2; AltName: Full=Cerebral protein 7; AltName: Full=Peanut-like protein 2; FUNCTION: Filament-forming cytoskeletal GTPase (By similarity). May play a role in cytokinesis (Potential). May play a role in platelet secretion. Isoform ARTS, but not the other isoforms, is required for the induction of cell death mediated by TGF-beta and by other apoptotic stimuli. SUBUNIT: Septins polymerize into heterooligomeric protein complexes that form filaments, and can associate with cellular membranes, actin filaments and microtubules. GTPase activity is required for filament formation (By similarity). Interacts with SEPT8. In a mesenchymal cell line, interacts with SEPT9 isoform 2 variants HNA Trp-106 and Phe-111, but not the wild type SEPT9. Isoform ARTS, but no other isoforms, interacts with XIAP after the induction of apoptosis. INTERACTION: Q8IUQ4:SIAH1; NbExp=2; IntAct=EBI-4372019, EBI-747107; P98170:XIAP; NbExp=4; IntAct=EBI-4372019, EBI-517127; SUBCELLULAR LOCATION: Cytoplasm (By similarity). Cytoplasm, cytoskeleton (By similarity). Note=In platelets, found in areas surrounding alpha-granules. SUBCELLULAR LOCATION: Isoform ARTS: Mitochondrion. Nucleus. Note=While predominantly localized in the mitochondria under resting conditions, isoform ARTS translocates into the nucleus after TGF-beta treatment and apoptosis induction. TISSUE SPECIFICITY: Widely expressed in adult and fetal tissues with highest expression in adult brain (at protein level), heart, liver and adrenal gland and fetal heart, kidney, liver and lung. Also expressed in colorectal cancers and malignant melanomas. Expressed in platelets. SIMILARITY: Belongs to the septin family.
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.

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.
