A PAK-activated linker for EGFR and FAK.
Transmembrane growth factor and integrin matrix receptors form multiprotein signaling complexes with FAK, a cytoplasmic cell motility-associated kinase. In a recent issue of Molecular Cell, Long et al. now show that a PAK-phosphorylated alternate-spliced isoform of the steroid receptor coactivator-3 (SRC-3Delta4) bridges EGFR and FAK, enhancing breast carcinoma cell migration and metastasis.
