The article focuses on Toxoplasma gondii effector ROP2 and the host cell interactions of parasites. It references a study by G. Labesse et al published in the 2009 issue of "Structure." It states that ROP2 serves as putative protein kinases, and contains conserved insertions and long amino-terminal extension. It also notes that various ROP2s adhere to the parasitophorous vacuole membrane and protein-binding capabilities.
