Kinesins are a family of motor proteins conserved throughout eukaryotes. In our present study we characterize a novel kinesin, Kinesin(CaaX), orthologs of which are only found in the kinetoplastids and not other eukaryotes. Kinesin(CaaX) has the CVIM amino acids at the C-terminus, and CVIM was previously shown to be an ideal signal for protein farnesylation in T. brucei. In this study we show Kinesin(CaaX) is farnesylated using radiolabeling studies and that farnesylation is dependent on the CVIM motif. Using RNA interference, we show Kinesin(CaaX) is essential for T. brucei proliferation. Additionally RNAi Kinesin(CaaX) depleted T. brucei are 4 fold more sensitive to the protein farneysltransferase (PFT) inhibitor LN-59, suggesting that Kinesin(CaaX) is a target of PFT inhibitors' action to block proliferation of T. brucei. Using tetracycline-induced exogenous tagged Kinesin(CaaX) and Kinesin(CVIMdeletion) (non-farnesylated Kinesin) expression lines in T. brucei, we demonstrate Kinesin(CaaX) is farnesylated in T. brucei cells and this farnesylation has functional effects. In cells expressing a CaaX-deleted version of Kinesin, the localization is more diffuse which suggests correct localization depends on farnesylation. Through our investigation of cell cycle, nucleus and kinetoplast quantitation and immunofluorescence assays an important role is suggested for Kinesin(CaaX) in the separation of nuclei and kinetoplasts during and after they have been replicated. Taken together, our work suggests Kinesin(CaaX) is a target of PFT inhibition of T. brucei cell proliferation and Kinesin(CaaX) functions through both the motor and farnesyl groups.
