Zyxin is a protein that in humans is encoded by the ZYX gene.^[1][2][3]

Function

Focal adhesions are actin-rich structures that enable cells to adhere to the extracellular matrix and at which protein complexes involved in signal transduction assemble. Zyxin is a zinc-binding phosphoprotein that concentrates at focal adhesions and along the actin cytoskeleton. Zyxin has an N-terminal proline-rich domain and three LIM domains in its C-terminal half. The proline-rich domain may interact with SH3 domains of proteins involved in signal transduction pathways while the LIM domains are likely involved in protein-protein binding. Zyxin may function as a messenger in the signal transduction pathway that mediates adhesion-stimulated changes in gene expression and may modulate the cytoskeletal organization of actin bundles. Alternative splicing results in multiple transcript variants that encode the same isoform.^[3]

Interactions

Zyxin has been shown to interact with:

• Actinin, alpha 1^[4][5]
• ENAH,^[6][7]
• LASP1,^[8]
• LATS1,^[9] and
• Vasodilator-stimulated phosphoprotein.^[7][10]
