ID:DIAP1_HUMAN DESCRIPTION: RecName: Full=Protein diaphanous homolog 1; AltName: Full=Diaphanous-related formin-1; Short=DRF1; FUNCTION: Acts in a Rho-dependent manner to recruit PFY1 to the membrane. Required for the assembly of F-actin structures, such as actin cables and stress fibers. Nucleates actin filaments. Binds to the barbed end of the actin filament and slows down actin polymerization and depolymerization. Required for cytokinesis, and transcriptional activation of the serum response factor. DFR proteins couple Rho and Src tyrosine kinase during signaling and the regulation of actin dynamics. Functions as a scaffold protein for MAPRE1 and APC to stabilize microtubules and promote cell migration (By similarity). Has neurite outgrowth promoting activity (By similarity). In hear cells, it may play a role in the regulation of actin polymerization in hair cells. The MEMO1-RHOA- DIAPH1 signaling pathway plays an important role in ERBB2- dependent stabilization of microtubules at the cell cortex. It controls the localization of APC and CLASP2 to the cell membrane, via the regulation of GSK3B activity. In turn, membrane-bound APC allows the localization of the MACF1 to the cell membrane, which is required for microtubule capture and stabilization. Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the control of cell shape. SUBUNIT: Homodimer. Interacts with the GTP-bound form of RHOA. Interacts with RHOC, PFY1, MAPRE1, BAIAP2 and APC. Interacts with SCAI (By similarity). Interacts with DCAF7, via FH2 domain. Interacts with NCDN (By similarity). INTERACTION: Q9Q2G4:ORF (xeno); NbExp=2; IntAct=EBI-3959709, EBI-6248094; SUBCELLULAR LOCATION: Cell membrane. Cell projection, ruffle membrane. Cytoplasm, cytoskeleton. Note=Membrane ruffles, especially at the tip of ruffles, of motile cells. TISSUE SPECIFICITY: Expressed in brain, heart, placenta, lung, kidney, pancreas, liver, skeletal muscle and cochlea. DOMAIN: The DAD domain regulates activation via by an autoinhibitory interaction with the GBD/FH3 domain. This autoinhibition is released upon competitive binding of an activated GTPase. The release of DAD allows the FH2 domain to then nucleate and elongate nonbranched actin filaments (By similarity). DISEASE: Defects in DIAPH1 are the cause of deafness autosomal dominant type 1 (DFNA1) [MIM:124900]. DFNA1 is a form of sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. SIMILARITY: Belongs to the formin homology family. Diaphanous subfamily. SIMILARITY: Contains 1 DAD (diaphanous autoregulatory) domain. SIMILARITY: Contains 1 FH1 (formin homology 1) domain. SIMILARITY: Contains 1 FH2 (formin homology 2) domain. SIMILARITY: Contains 1 GBD/FH3 (Rho GTPase-binding/formin homology 3) domain. SEQUENCE CAUTION: Sequence=BAB14533.1; Type=Miscellaneous discrepancy; Note=Intron retention; Sequence=BAD92719.1; Type=Erroneous initiation; Note=Translation N-terminally shortened; WEB RESOURCE: Name=Hereditary hearing loss homepage; Note=Gene page; URL="http://webhost.ua.ac.be/hhh/";
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.
