Definition

In living things movement is generated by a range of molecular motors that include flagella/cilia, kinesin and dynein movement on microtubules, and actomyosin-based systems. Malaria parasites of the genus Plasmodiumand other members of the Apicomplexa phylum use an actomyosin motor for motility and invasion of host cells and tissues. The malaria parasite has both intracellular and extracellular stages during its life cycle. Some of these extracellular forms, known as zoites, are polarized cells specially adapted for migration through and invasion of host cells. The zoite stages all share a common structure, including a variety of secretory organelles at the apical end of the cell, as well as a distinctive double-membrane structure called the inner membrane complex (IMC) that is located immediately below the cell plasmalemma. These apical organelles and the IMC are key to...
