Cell cycle transitions are generally triggered by variation in the activity of cyclin-dependent kinases (CDKs) bound to cyclins. Malaria-causing parasites have a life cycle with unique cell-division cycles, and a repertoire of divergent CDKs and cyclins of poorly understood function and interdependency. We show thatPlasmodium bergheiCDK-related kinase 5 (CRK5), is a critical regulator of atypical mitosis in the gametogony and is required for mosquito transmission. It phosphorylates canonical CDK motifs of components in the pre-replicative complex and is essential for DNA replication. We also provide evidence for indirect regulation of the concomitant M-phase progression. During a replicative cycle, CRK5 stably interacts with a singlePlasmodium-specific cyclin (SOC2), although we obtained no evidence of SOC2 cycling by transcription, translation or degradation. Our results provide evidence that duringPlasmodiummale gametogony, this unique cyclin/CDK pair fills the functional space of multiple eukaryotic cell-cycle kinases controlling DNA replication and M-phase progression.
