Figure S3. Localization of sulfotransferases is not changed by adaptor protein-1 knockdown or knockout.

(A, C) HeLa cells stably expressing TPST1-EGFP or TPST2-EGFP were transfected with non-targeting siRNA (control-kd) or with siRNA silencing expression of μ1A as described in Fig 1. Cells were then fixed, stained for EEA1, and imaged by fluorescence microscopy. (B, D) Adaptor protein-1γ knockout HeLa cells were transiently transfected with plasmids encoding TPST1-EGFP or TPST2-EGFP and prepared as in (A, C). Bar: 10 μm.
