(A-F) Pull down assays were performed using GST fusions encoding the indicated AC-LL signals of the different LRPs with Sf9 cell-expressed GGAs (A, C, D, and E-left panel), or GST-GGA2 VHS with HEK 293 cell-expressed wild-type and mutant LRPs and LERP (B, E-right panel, and F). Ponceau staining of the membrane (A, D, and E-left panel) indicates that similar amounts of the various GST-fusions were used.
