(a) MS intensities of Kank1-4 in the FA-enriched sub-proteome and total proteome of wild-type mouse kidney fibroblasts (mean ± s.d.; n = 3 independent MS measurements). (b) Western blot analysis of Kank2 and β1 integrin (Itgb1) in cells expressing scrambled (shScr) and Kank2-specific shRNAs. Actin served to control protein loading. (c) Western blot analysis of Kank2 before and after shRNA-mediated knockdown using polyclonal anti-Kank2, and of indicated GFP-tagged Kank2 constructs using anti-GFP antibodies, respectively. Vinculin is used as loading control.
