Abstract
The regulation of gene expression in Plasmodium spp., the causative agents of malaria, relies on precise transcriptional control. Malaria parasites encode a limited repertoire of sequence-specific transcriptional regulators dominated by the apicomplexan APETALA 2 (ApiAP2) protein family. ApiAP2 DNA-binding proteins play critical roles at all stages of the parasite life cycle. Recent studies have provided mechanistic insight into the functional roles of many ApiAP2 proteins. Two major areas that have advanced significantly are the identification of ApiAP2-containing protein complexes and the role of ApiAP2 proteins in malaria parasite sexual development. In this review, we present recent advances on the functional biology of ApiAP2 proteins and their role in regulating gene expression across the blood stages of the parasite life cycle.
