Western blot analysis of ZYX over-expressed 293 cell line, cotransfected with ZYX Validated Chimera RNAi ( Cat # H00007791-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with ZYX monoclonal antibody (M01), clone 2C10-4A7 (Cat # H00007791-M01 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
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. [provided by RefSeq
