Targeted deletion of Plasmodium knowlesi Duffy binding protein confirms its role in junction formation during invasion.

abstract：:Microtubules are key players in the biology of Trypanosomatid parasites, not only as classical components of the mitotic spindle, microtubule-organizing centres and flagellum but also as the essential constituent of the cytoskeleton. Their length dynamics are regulated by, among others, microtubule-severing proteins. ...
