B. Overexpression of FLAG-DnaJC5 induces extracellular release of wildtype (WT) and A53T α-synuclein in HEK293T cells. Extracellular protein levels shown by dot blot (quantification below, mean ±SEM, n=3 ***p<0.001, ** p<0.01 by one-way analysis of variance with Tukey's multiple comparison post-hoc analysis) and intracellular proteins levels were analyzed by Western blot, DnaJC5 was detected by FLAG antibody.
