Plasmodium falciparum dynein light chain 1 interacts with actin/myosin during blood stage development.

ABSTRACT: Dynein light chain 1 (LC1), a member of the leucine-rich repeat protein family, has been shown to be engaged in controlling flagellar motility in Chlamydomonas reinhardtii and Trypanosoma brucei via its interaction with the dynein gamma heavy chain. In Plasmodium falciparum, we have identified the LC1 ortholog, designated Pfdlc1. Negative attempts to disrupt the dlc1 gene by reverse genetic approaches in both P. falciparum and P. berghei suggest either its essentiality for parasite survival or the inaccessibility of its locus. Expression studies revealed high levels of DLC1 protein in late trophozoites and schizonts, pointing to an unexpected role of this protein in blood-stage parasites as they do not have flagella. Interactions studies and co-immunoprecipitation experiments revealed that
