| Research Abstract |
One of the small GTPase, PfRab5a, was previously reported that involvement of endocytosis of erythrocyte cytosol. This work shows that another Rab5 isotype, Rab5b, possesses conserved motif with myristoilation site in N-terminus. Rab5b homologue is presented in Plasmodium and Toxopasma but not in Cryptosporidium, Paramecium and Tetrahymena in protozoa classified in Alveolata. Although expression of PfRab5b was low among three Rab5 isotypes, PfRab5b was expressed in erythrocytic stage. Expression of recombinant protein of PfRab5b was effective when an artificial gene appropriate for E. coli K12 codon was used.
