GEXP18 and PfPHIST_0801 are J-dot proteins. (A) Immunofluorescence using the J-dot marker PfHsp70x shows good colocalization with the GEXP18GFP chimera. (B) Immunofluorescence using the J-dot marker PfHsp70x shows good colocalization with PfPHIST_0801GFP. 70x, PfHsp70x; DIC, differential interference contrast, PHISTC, PfPHIST_0801. PfHsp70x and PfGEXP18 are found in a common protein complex. As PfGEXP18 is only found at the J-dots (A), this entire complex is likely to be localized to the J-dots. There is a good colocalization between PfPHIST_0801 and PfHsp70x (B) suggesting that PfPHIST_0801, as well as PfGEXP18, localizes to the J-dots.Zhang Q, Ma C, Oberli A, Zinz A, Engels S, Przyborski JM.
