The multifaceted roles of Myb domain-containing proteins in apicomplexan parasites

Curr Opin Microbiol. 2023 Oct 20;76:102395. doi: 10.1016/j.mib.2023.102395. Online ahead of print.ABSTRACTApicomplexan parasites are a large and diverse clade of protists responsible for significant diseases of humans and animals. Central to the ability of these parasites to colonize their host and evade immune responses is an expanded repertoire of gene-expression programs that requires the coordinated action of complex transcriptional networks. DNA-binding proteins and chromatin regulators are essential orchestrators of apicomplexan gene expression that often act in concert. Although apicomplexan genomes encode various families of putative DNA-binding proteins, most remain functionally and mechanistically unexplored. This review highlights the versatile role of myeloblastosis (Myb) domain-containing proteins in apicomplexan parasites as transcription factors and chromatin regulators. We explore the diversity of Myb domain structure and use phylogenetic analysis to identify common features across the phylum. This provides a framework to discuss functional heterogeneity and regulation of Myb domain-containing proteins particularly emphasizing their role in parasite differentiation.PMID:37866202 | DOI:10.1016/j.mib.2023.102395
