Regulation of Plasmodium falciparum cell cycle involving Cyclins and Cyclin Dependent Kinases

ABSTRACT

@#Protein kinases (PKs) are regulators of protein phosphorylation in many infectious diseases, including malaria. However, the cellular functions of majority of PKs in Plasmodium falciparum remain unknown. The mechanisms involved in P. falciparum cell cycle progress are not fully understood. The activation of cyclin-dependent kinases (CDKs), which constitute a PK family that includes crucial regulators of cell cycle progression in eukaryotes, is strictly being coordinated by the interaction with specific cyclins at well-defined points within the cell cycle. These cyclin/CDK complexes are very well characterised in humans, but little is known in P. falciparum. This review expand our understanding of the characteristic of CDKs and cyclins in P. falciparum, and paves the way for further investigations on the precise molecular role of these crucial regulatory proteins in mosquito and human. This represents a valuable step towards the elucidation of cell cycle control mechanisms in malaria parasites.
