. "SEQUENCE 1164 AA; 126551 MW; E6C7AE1FB8DC3FC7 CRC64;"^^ . "FUNCTION: Required for the assembly of F-actin structures, such as stress fibers. Depends on the Rho-ROCK cascade for its activity. Contributes to the coordination of microtubules with actin fibers and plays a role in cell elongation. Acts synergistically with ROCK1 to promote SRC-dependent non-apoptotic plasma membrane blebbing. SUBUNIT: Self-associates via the FH2 domain. Binds to F-actin via its N-terminus. Binds to the cytoplasmic domain of CD21 via its C- terminus. Interacts with ROCK1 in a Src-dependent manner. SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, cytoskeleton. Cell projection, bleb. Note=Predominantly cytoplasmic. TISSUE SPECIFICITY: Ubiquitous. Highly expressed in spleen. 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. PTM: Phosphorylated by ROCK1. SIMILARITY: Belongs to the formin homology family. 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. GENE SYNONYMS:FHOD1 FHOS FHOS1.
