Zyxin, a cytosolic protein containing 3 LIM zinc-binding domains, associates with the actin cytoskeleton near the adhesion plaques. Zyxin localizes to stress fibers, cell-cell junctions and colocalizes with vinculin, paxillin and VASP at focal adhesions but not at the tips of lamellipodia. Zyxin is involved in the regulation of actin dynamics and is a likely component of the signal transduction pathway mediating adhesion-stimulated changes in gene expression. Zyxin displays an actin nucleating activity that is dependent on its amino terminal proline-rich motifs and independent of Arp2/3 complex. Zyxin appears to function as an adaptor or docking protein to organize protein complexes important for regulated actin cytoskeleton dynamics.
