In this study we investigated alterations in the plasma membrane (PM)-associated proteome of DAOY medulloblastoma cells. We used a surface biotinylation approach to label PM-associated proteins. We enriched for biotinylated proteins by streptavidin-pull-down and determined the composition by mass-spectrometry. We compared CRISPR/CAS9 control cells and CRISPR/CAS9 MAP4K4 (MAP4K4 depletion) cells under starvation and after 30 min stimulation with 20 ng/ml HGF. We performed two group analyses of all conditions.
