**Background of PPP2R3A Recombinant Protein**
PPP2R3A (Protein Phosphatase 2 Regulatory Subunit B'' Alpha) is a regulatory component of the serine/threonine protein phosphatase 2A (PP2A) complex, a critical enzyme involved in diverse cellular processes, including cell cycle regulation, signal transduction, and apoptosis. As part of the B'' family (also termed the B56 subfamily), PPP2R3A functions as a scaffolding subunit that directs PP2A’s substrate specificity and subcellular localization by forming distinct holoenzyme complexes with catalytic (C) and structural (A) subunits.
Recombinant PPP2R3A is produced through molecular cloning and expression systems (e.g., *E. coli* or mammalian cells), enabling controlled studies of its structure-function relationships. Its recombinant form typically retains conserved domains, such as the heat-repeat motifs essential for binding PP2A core enzymes and regulatory partners. Research highlights its role in modulating PP2A activity toward specific targets, including proteins involved in Wnt/β-catenin signaling, DNA damage response, and cytoskeletal dynamics.
Dysregulation of PPP2R3A has been implicated in diseases, including cancers and neurodegenerative disorders, underscoring its therapeutic relevance. For instance, altered expression or mutations in PPP2R3A may disrupt PP2A-mediated tumor suppression or tau dephosphorylation in Alzheimer’s disease. Recombinant PPP2R3A serves as a vital tool for dissecting PP2A’s regulatory mechanisms, screening potential drugs targeting PP2A pathways, and exploring its interactions with viral proteins or oncogenic kinases.
Overall, PPP2R3A recombinant protein bridges structural, biochemical, and biomedical research, offering insights into PP2A’s multifaceted roles in health and disease.
