(A) S2 cells expressing RDH/CH2064-GFP were treated with the protein synthesis inhibitor cycloheximide (CHX) for the indicated time (h: hours). The level of RDH/CH2064-GFP was determined by western blotting using anti-GFP antibody. Tubulin was used as loading control. (B) Quantification of the relative RDH/CH2064-GFP protein levels in (A). Error bars represent ± SEM.
