YLMY motif tyrosine residue does not function in clathrin-mediated endocytosis. (A) The cytotoxicity of chlorpromazine (CPZ). (B, C) BSR-T7/5 cells were pretreated with 10 μm CPZ at 37°C for 1 h and incubated with viruses for 1 h. DMSO was used as a negative control. The cells were collected at 6 hpi for qRT-PCR and Western blot to test the invasion efficiency of viruses. Results are presented as the mean ± SD of data from three independent experiments.
