Localization of the Diaphanous-related formin Daam1 to neuronal dendrites.

The Rho family of small GTPase proteins are involved in the formation and maintenance of neuronal dendrites. In this study, we show that Daam1, a member of the Diaphanous-related formin protein family and a downstream effector for RhoA, is localized to the dendrites of hippocampal neurons. Immunoblot analysis showed that Daam1 is enriched in the mouse hippocampus and co-fractionates in brain lysates with dendritic and synaptic proteins.
