Babesia gibsoni: molecular cloning and characterization of Rab6 and Rab11 homologues. Academic Article uri icon

abstract

  • Members of the Rab subfamily of GTPases have been implicated as important components in vesicle trafficking in the eukaryotes, individual Rab proteins have a remarkable degree of specific subcellular localization. As a first step towards developing a set of compartment specific probes for studying protein trafficking in Babesia-infected erythrocyte, here we describe the cloning and characterization of Rab6 and Rab11 gene homologues in Babesia gibsoni (BgRab6 and BgRab11). The deduced amino acid sequence of both BgRab6 and BgRab11 contained the highly conserved GTP-binding consensus sequence and C-terminal cysteines. Northern blotting analysis of total RNA hybridized a 1.3 kb band on both BgRab6 and BgRab11 probed blots consistent with the expected size. Using a GTP-binding assay we demonstrated that Escherichia coli expressed recombinant BgRab6 and BgRab11 were able to bind GTP. BgRab6 and BgRab11 represent the first two molecular markers of B. gibsoni.
