Summary of research interest:

Cytoskeleton  in neurodevelopment and neurodegeneration:
The survival of neurons may be affected by abnormalities in their processes called neurites.  Extension of normal neurites requires coordinated interactions between cytoskeletal networks of microfilaments (composed of F-actin) and microtubules (formed by tubulin) in growth cones, structures at the tip of growing neurites.  Capping protein (CP) regulates F-actin assembly.  Mutations in either alpha or beta CP subunit result in demise of photoreceptors in Drosophila.  However, the function of CP subunits in mammalian neurons remains unclear.  We have shown that, surprisingly, the neuronal CP beta subunit, Capzb2, inhibits microtubule polymerization by direct interaction with tubulin.  This function of Capzb2 is indispensable for the normal shape of growth cones and the appropriate length of neurites.
