(A) Colocalization of TgClpB3-FLAG with the marker TgACP-HA suggests that TgClpB3 is targeted to the apicoplast of T. gondii. (B) TgClpB3 is a membrane-associated protein. Proteins were extracted from RH-WT and either separated into soluble (S) and membrane pellet (P) fractions by sodium carbonate treatment or into soluble (S) and detergent (D) phases by Triton X-114 phase partitioning. Total protein extract (T) is shown in the first lane. (C) Western blot detection of TgClpB3 in extracellular parasites treated at 37°C, 43°C, or 46°C for 4 h.
