Binds to disheveled (Dvl) and Rho, and mediates Wnt-induced Dvl-Rho complex formation. May play a role as a scaffolding protein to recruit Rho-GDP and Rho-GEF, thereby enhancing Rho-GTP formation. Can direct nucleation and elongation of new actin filaments. Involved in building functional cilia (PubMed:16630611, PubMed:17482208). Involved in the organization of the subapical actin network in multiciliated epithelial cells (By similarity). Together with DAAM2, required for myocardial maturation and sarcomere assembly (By similarity). During cell division, may regulate RHOA activation that signals spindle orientation and chromosomal segregation. {ECO:0000250|UniProtKB:B0DOB5, ECO:0000250|UniProtKB:Q8BPM0, ECO:0000269|PubMed:16630611, ECO:0000269|PubMed:17482208}. This is the function of DAAM1 (dishevelled associated activator of morphogenesis 1, ENSG00000100592).
