Figure 3. PAK4 associates with the CCT and Arp2/3 complexes.

Figure 3

(A) Several subunits of the Arp2/3 and CCT complexes were identified in the PAK4 interactome. White nodes: proteins passed QMS cut-off; Grey nodes: proteins appeared in MS but did not pass the QMS cut-off; Darker grey node: not in the MS list. (B) After GFP-Trap IP of H1299 cell lysates transiently expressing EGFP (control) or EGFP-PAK4, samples were subjected to immunoblot analysis for the indicated proteins. The upper panel is blotted with anti-CCTε, the middle panel with anti-ARPC2, while anti-GFP was used to control the IP efficiency in the lower panel. Input lanes are direct immunoblot of the used cell lysates. (C) After anti-CCTε IP of H1299 cell lysates transiently expressing EGFP-PAK4, blots were probed with an anti-GFP antibody in the upper panel. Anti-CCTε was used to control the IP efficiency in the lower panel. Input lane shows direct immunoblotting of the used lysate.
