A formin-homology (FH) protein, first identified in Drosophila (Castrillon & Wasserman, 1994), and subsequently in mammals (Watanabe et al, 1997). Diaphanous (or mDia1), coordinates both the actin and the microtubule systems in an incompletely understood mechanism involving Rac, Rho and their various effectors (Tsuji et al, 2002).
