Probably involved in the organization of the actin cytoskeleton. May act downstream of CDC42 to induce actin filament assembly leading to cell shape changes. Induces pseudopodia formation in fibroblasts in a CDC42-dependent manner.
Subcellular locations: Endomembrane system, Cytoplasm, Cytoskeleton
Highly expressed in the heart. Weakly expressed in the pancreas and liver.
