(A) Schematic of zyxin and tandem LIM sequences. (B) Western blot of stable MDCK cell lines expressing no exogenous zyxin (WT), the full-length zyxin (Zyx), and single (s), tandem dimer (td), and tandem trimer (tri) LIM sequence. All constructs are tagged with GFP. The membranes were blotted with GFP (top) and tubulin (bottom). (C) Live-cell images of MDCK cells expressing GFP-tagged full-length zyxin, single LIM, tandem dimer LIM, and tandem trimer LIM constructs. Scale bar 10 µm.
