AP2XII-2 binding sites in Toxoplasma gondii

Developmental regulation of the intracellular parasite Toxoplasma gondii is an understudied topic despite being central for a bid to control its dissemination around the globe. Of particular neglect are the factors that contribute to its sexual development. While it has previously been shown that generalized transcriptional repression machinery plays an important role in silencing spurious gene expression of sexually-committed parasites, the specific factors that target the generalized machinery to genetic loci remains unexplored. Here, we uncover that a member of the AP2 transcription factor family, AP2XII-2, is targeted to genomic loci that are associated with sexually-committed parasites along with the generalized regulators of transcriptional silencing, HDAC3 and MORC. Despite widespread association with gene promoters, AP2XII-2 is required for silencing of relatively few genes. We place two genes associated with sexual development downstream of AP2XII-2 control, transcription factor AP2X-10 and the amino acid hydroxylase AAH1. Dissecting gene regulatory pathways of Toxoplasma sexual development will likely be essential for controlling Toxoplasma dissemination in the future. Overall design: Toxoplasma gondii with AP2XII-2 tagged with (HA-AID) were collected and processed by CUT&Tag protocol to determine AP2XII-2 binding sites genome-wide in tachyzoites
