Recombinant production, purification and crystallization of the Toxoplasma gondii coronin WD40 domain.

ABSTRACT: Toxoplasma gondii is one of the most widely spread parasitic organisms in the world. Together with other apicomplexan parasites, it utilizes a special actin-myosin motor for its cellular movement, called gliding motility. This actin-based process is regulated by a small set of actin-binding proteins, which in Apicomplexa comprises only 10-15 proteins, compared with >150 in higher eukaryotes. Coronin is a highly conserved regulator of the actin cytoskeleton, but its functions, especially in parasites, have remained enigmatic. Coronins consist of an N-terminal actin-binding β-propeller WD40 domain, followed by a conserved region, and a C-terminal coiled-coil domain implicated in oligomerization. Here, the WD40 domain and the conserved region of coronin from T. gondii were produced recombinan
