The role of the motor protein myosin A in the pathogenesis of Toxoplasma gondii has been examined by Meissner et al. (p. 837), who regulated the expression of a target protein to maintain the possibility of parasite propagation in the presence of a mutation of a gene required for invasion and parasite growth. They confirmed that myosin A is required to power the invasion of host cells and is a virulence factor in a mouse model system.
