How Protein kinase A (PKA) is reset to a basal state following 3’5’cyclic adenosine monophosphate(cAMP)-mediated activation is unknown. Here we describe the mechanism of cAMP-PKA signal termination leading to reset of PKA by holoenzyme formation through the obligatory action of phosphodiesterases (P...

Phenotypic switching from tachyzoite to bradyzoite and vice versa is the fundamental mechanism underpinning the pathogenicity and adaptability of the protozoan parasite Toxoplasma gondii. Accumulation of cytoplasmic starch granules is a hallmark of the quiescent bradyzoite stage. The regulatory fact...

Toxoplasma gondii is a significant pathogen affecting both humans and animals, with clinical symptoms primarily driven by the uncontrolled proliferation of tachyzoites. In this study, we reveal the essential role and functional plasticity of the PP2A-2 holoenzyme in orchestrating daughter cell emerg...

Protein kinase A (PKA) is a conserved kinase essential for many biological processes linked to growth, development and metabolism. The PKA catalytic subunit is expressed as multiple isoforms in diverse eukaryotes; however, their contribution to ensuring specificity in response to environmental cues ...
