A delta-catenin signaling pathway leading to dendritic protrusions.

Abstract excerpt

Delta-catenin is a synaptic adherens junction protein pivotally positioned to serve as a signaling sensor and integrator. Expression of delta-catenin induces filopodia-like protrusions in neurons. Here we show that the small GTPases of the Rho family act coordinately as downstream effectors of delta-catenin. A dominant negative Rac prevented delta-catenin-induced protrusions, and Cdc42 activity was dramatically...
