Figure 4From: Parkin-mediated ubiquitination of mutant glucocerebrosidase leads to competition with its substrates PARIS and ARTSOverexpression of PARIS leads to stabilization of mutant GCase. (A) SHSY5Y cells stably expressing WT or N370S and L444P mutant GCase were transfected with the indicated amounts of GFP-PARIS expressing plasmid. Sixteen hours later, cell lysates were prepared and subjected to western blot analysis. The corresponding blot was interacted with anti-GFP antibody, anti-myc and anti-ERK antibodies, as a loading control. (B) To quantify the results, the blots were scanned and GCase intensity at each lane was divided by the intensity of ERK1/2 in the same lane. The value obtained for WT-GCase was considered as 1. The results represent the mean ± SEM of 3 independent experiments. *P < 0.05, **P < 0.01 in Student t-test.Back to article page
