CC -!- FUNCTION: Required for cytokinesis in both mitosis and meiosis. Has a CC role in actin cytoskeleton organization and is essential for many, if CC not all, actin-mediated events involving membrane invagination. May CC serve as a mediator between signaling molecules and actin organizers at CC specific phases of the cell cycle. Possible component of the CC contractile ring or may control its function. CC {ECO:0000269|PubMed:10751177, ECO:0000269|PubMed:7821209}. CC -!- SUBUNIT: May interact (via CBD/FH3 domain) with Rho1. CC {ECO:0000269|PubMed:23853710}. CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton CC {ECO:0000269|PubMed:7821209}. Cleavage furrow CC {ECO:0000269|PubMed:7821209}. Apical cell membrane CC {ECO:0000269|PubMed:23853710}. Note=Localizes to the site where the CC metaphase furrow is anticipated to form, to the growing tip of CC cellularization furrows, and to contractile rings (PubMed:7821209). CC Recruited to the apical cell membrane of epithelial cells in a Rho1 CC dependent manner, enhanced by phosphatidylinositol 4,5-bisphosphate CC (PtdIns[4,5]P(2)) enrichment established by sktl/skittles and Pten CC (PubMed:23853710). {ECO:0000269|PubMed:23853710, CC ECO:0000269|PubMed:7821209}. CC -!- DEVELOPMENTAL STAGE: In stage 15 embryos expressed in epithelial cells CC of various tubular tissues including trachea, hindgut and salivary CC gland (at protein level). {ECO:0000269|PubMed:23853710}. CC -!- DOMAIN: The DAD domain regulates activation via by an autoinhibitory CC interaction with the GBD/FH3 domain. This autoinhibition is released CC upon competitive binding of an activated GTPase. The release of DAD CC allows the FH2 domain to then nucleate and elongate nonbranched actin CC filaments (By similarity). DAD-mediated autoinhibition negatively CC regulates dia localization to the apical cell cortex (PubMed:23853710). CC {ECO:0000250, ECO:0000269|PubMed:23853710}. CC -!- DOMAIN: The N terminal basic region is enriched in basic amino acids CC that may mediate interaction with negatively charged CC phosphatidylinositol 4,5-bisphosphate (PtdIns[4,5]P(2)). It is CC required, but not sufficient on its own, for efficient apical CC localization in polarized epithelial cells. CC {ECO:0000269|PubMed:23853710}. CC -!- DOMAIN: The GTPase binding domain (GBD) probably mediates interaction CC with Rho1 required for disruption of autoinhibition and targeted CC recruitment to the apical membrane of polarised epithelial cells. CC {ECO:0000269|PubMed:23853710}. CC -!- SIMILARITY: Belongs to the formin homology family. Diaphanous CC subfamily. {ECO:0000305}.
