Migfilin localization in kindlin-2 knockdown fibroblasts. NIH3T3 fibroblasts were infected with lentivirus containing control (SC, scrambled) shRNA or kindlin-2 (K2) shRNA. A, these cell lysates were probed for endogenous kindlin-2 using FLNa as a loading control. B, using lysate of CHO cells transfected with FLAG-kindlin-1 and lysates of scramble (SC) or kindlin-2 knockdown keratinocyte (KT) as positive controls, SC or K2 knockdown 3T3 lysates were probed for endogenous kindlin-1. C, scramble control cells were plated on fibronectin and transfected with GFP-migfilin full-length (WT), then fixed and stained for endogenous vinculin. D and E, kindlin-2 knockdown 3T3 cells were transfected with GFP-migfilin WT or migfilin ΔLIM2,3 (F) and stained for endogenous vinculin or F-actin. Scale bar = 20 μm; inset scale bar, 5 μm.
