Microtubule inner proteins of <i>Plasmodium</i> are essential for transmission of malaria parasites.

ABSTRACT: Microtubule inner proteins (MIPs) are microtubule-associated proteins that bind to tubulin from the luminal side. MIPs can be found in axonemes to stabilize flagellar beat or within cytoplasmic microtubules. Plasmodium spp. are the causative agents of malaria that feature different parasite forms across a complex life cycle with both unique and divergent microtubule-based arrays. Here, we investigate four MIPs in a rodent malaria parasite for their role in transmission to and from the mosquito. We show by single and double gene deletions that SPM1 and TrxL1, MIPs associated with subpellicular microtubules, are dispensable for transmission from the vertebrate host to the mosquito and back. In contrast, FAP20 and FAP52, MIPs associated with the axonemes of gametes, are essential for t
