Updated project metadata. Drosophila S2 cells were transfected with RasGAP(WT), RasGAP(SH2*32*) and GFP control. 4 mg of S2 cell lysate was used to pulldown LAP and GFP tagged constructs using GFP-Trap. The pulled down fraction was loaded on SDS-PAGE gels and coomassie stained before several bands (a-u) from two independent but parallel experiments were excised and subjected to MS analysis.
