Figure 1From: Farnesylation or geranylgeranylation? Efficient assays for testing protein prenylation in vitro and in vivoWestern blots and TLC scanning results for Rap2A with radioactive prenyl anchor precursors. Western Blot and corresponding scans from TLC linear analyzer of wildtype GST-Rap2A-fusion protein translated with [3H]mevalonic acid (lane 1), GST-Rap2A C180A with [3H]mevalonic acid (lane 2), GST-Rap2A with [3H]FPP (lane 3) and GST-Rap2A with [3H]GGPP (lane 4). There is significant incorporation of a product of mevalonic acid (lane 1) as well as FPP (lane 3), while incorporation of GGPP is close to the detection limit (lane 4), suggesting that Rap2A is primarily a farnesylation target.Back to article page
