p120-catenin protein level is enhanced following CRK-SH3N domain expression. Western blots demonstrating the expression levels of CRK-SH2 and CRK-SH3N domains in H157, A549, and Rh2 NSCLC cells. Cells were stably transfected with plasmid constructs expressing empty vector, CRK-SH2 domain, or CRK-SH3N domain fused with a flag tag. Additionally, the relative p120-catenin expression level in each group is demonstrated.
