Disheveled-associated activator of morphogenesis 1 is a protein that in humans is encoded by the DAAM1 gene.[1][2][3] Evidence of alternative splicing has been observed for this gene but the full-length nature of these variants has not been determined.

## Function

[edit | edit source]

Cell motility, adhesion, and cytokinesis, and other functions of the cell cortex are mediated by the reorganization of the actin cytoskeleton 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 GTPase Rho, 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.[3]

## Clinical significance

[edit | edit source]

The deletion of a single copy of this gene has been associated with congenital heart defects.[4]
