A potential hexose transporter gene expressed predominantly in the bloodstream form of Trypanosoma brucei.
A cDNA cloned from Trypanosoma brucei brucei codes for a putative membrane protein which is homologous to the erythrocyte glucose transporter and several other sugar transporters from Escherichia coli, yeast, algae and Leishmania. This cDNA hybridizes to a 2.3-kb mRNA that accumulates to a much higher degree in the bloodstream mammalian form than in the procyclic insect form of the parasite. The correlation between the expression of this gene and the hexose metabolism of Leishmania enriettii and T. brucei suggest that these 2 related genes probably encode hexose transporters. The gene encoding this mRNA is a member of a multigene family. The putative hexose transporter gene is highly conserved among Kinetoplastidae, indicating an important role for this protein in the parasite life cycle.
