Colocalization of NHERF-2 and β-catenin. A431 cells expressing NHERF-2 and the constructs shown in Figure 2A were fixed on coverslips and stained for β-catenin (red), using rabbit anti-β-catenin and NHERF-2 (green) using 32B6 (against PDZ II) in b, f, h, j, and l, 9E10 in d and n, and rabbit anti-myc in p. A431 cells expressing the C terminus of NHERF-2 were stained for ezrin (red) in o.
