Initiation of translation and cellular localization of Theileria annulata casein kinase IIalpha: implication for its role in host cell transformation.

Theileria annulata and T. parva are protozoa that infect bovine leukocytes which leads to subsequent transformation and uncontrolled proliferation of these cells. It has been proposed that the CKIIalpha subunit of T.

Characterization of a polymorphic Theileria annulata surface protein (TaSP) closely related to PIM of Theileria parva: implications for use in diagnostic tests and subunit vaccines.

Theileria annulata is a tick-transmitted protozoan that causes tropical theileriosis, an often fatal leukoproliferative disorder of cattle. To characterize and identify parasite proteins suitable as diagnostic antigens and/or vaccine candidates, a cDNA clone encoding a macroschizont stage protein was isolated and characterized (here designated TaSP). The gene, present as a single copy within the parasite genome, is transcribed in the sporozoite and schizont stage and codes for a protein of about 315 amino acids, having a predicted molecular weight of 36 kDa.
