Babesia divergens: cloning of a Ran binding protein 1 homologue.

Babesia divergens is an Apicomplexa transmitted to bovines by its acarian vector, the tick I. ricinus. Babesia divergens merozoites have an intraerythrocytic development in the blood of infected mammals. The nucleocytoplasmic transport system in this parasite is not yet characterized and no protein involvement in such transport has been described. In this report, we describe the cloning of a protein that shares important homologies with Ran binding protein 1. This protein in Eukaryote belongs to the nucleocytoplasmic transport system.
