Fig. 5. CP orientation in
-tubulin, PACRG and PFR2 RNAi mutant cell lines. (A) The remaining CP microtubule in 9+1 axonemes resulting from
-tubulin ablation has a random orientation. (B) Knockdown of PACRG severely disrupts outer doublet microtubules, but only partially removes CP constraint in X+2 axonemes. (C) Immotility as a result of PFR2 ablation does not affect CP orientation. (D) Radial distribution of the doublets and the CP microtubules in transverse sections of axonemes from the induced
-tubulin and PACRG RNAi trypanosomes.
