Toxoplasma gondii is a prevalent pathogenic parasite that infects approximately 25 percent of the US population. For the parasite to successfully establish and maintain infection in its host, properly controlled regulation of gene expression is critical. One way Toxoplasma regulates gene expression is through modification of histone proteins that bind to DNA and can control gene accessibility. Acetylation is a modification that is added to histones that changes chromatin structure to enhance gene activation. Histone acetylation can also regulate gene expression by recruitment of important regulators such as bromodomain proteins (BDP). A previous study showed that loss of the bromodomain …
