Figure 8. Proteomic analysis of Tg-AGO complexes.

Figure 8

(A) Tg-AGO complexes were immunoprecipitated using Flag antibodies. The co-immunoprecipitated proteins were analysed using mass spectrometry (see Table 1 and Supplemental Table S1). Molecular weight markers are indicated on the left. (B) Transgenic parasites expressing ectopically HAFlag-TgAGOFL were lysed and whole-cell-extracts prepared in the absence or presence (+RNase T1) of ribonuclease T1. HAFlag-TgAGOFL was immunoprecipitated using anti-FLAG beads and flag peptide-eluted fractions were separated by SDS-polyacrylamide gel electrophoresis (4% to 12%), and visualized by silver staining. Molecular weight markers are indicated on the left. (C) Flag-immunopurified fractions from HAFlag-TgAGOFL and HAFlag-TgAGODRGG RNase T1-treated and untreated samples were analyzed by Western blot using a home-made anti-Tg-KSRP antibody. (D) Sedimentation characteristics of Tg-KSRP compared to HAFlag-TgAGOFL.
