Disheveled-associated activator of morphogenesis 1 is a protein that in humans is encoded by the DAAM1gene. Evidence of alternative splicing has been observed for this gene but the full-length nature of these variants has not been determined.
Cell motility, adhesion, and cytokinesis, and other functions of the cell cortex are mediated by the reorganization of the actincytoskeleton and recent evidence suggests a role for formin homology (FH) proteins in these processes. The protein encoded by this gene contains FH domains and belongs to a novel FH protein subfamily implicated in cell polarity. Wnt/Fz signaling activates the small GTPaseRho, a key regulator of cytoskeleton architecture, to control cell polarity and movement during development. Activation requires Dvl-Rho complex formation, an assembly mediated by this gene product, which is thought to function as a scaffolding protein.
