**Background of PPP3CA Recombinant Protein**
PPP3CA encodes the catalytic subunit A of calcineurin, a calcium/calmodulin-dependent serine/threonine protein phosphatase. Calcineurin plays a pivotal role in calcium-mediated signaling pathways, regulating diverse physiological processes such as immune response, neuronal development, and cardiac function. The PPP3CA protein, in complex with regulatory subunit B (calcineurin B), dephosphorylates substrates like NFAT (nuclear factor of activated T-cells), enabling their translocation to the nucleus to modulate gene expression. Dysregulation of PPP3CA is linked to pathologies including neurodegenerative diseases, cardiac hypertrophy, and autoimmune disorders.
Recombinant PPP3CA protein is engineered using heterologous expression systems (e.g., *E. coli*, mammalian cells) to produce purified, functional enzyme for research and therapeutic applications. It typically retains phosphatase activity and is utilized to study calcineurin’s enzymatic mechanisms, substrate interactions, and inhibition by immunosuppressants like tacrolimus (FK506) or cyclosporine A. Structurally, recombinant PPP3CA often includes affinity tags (e.g., His-tag) for simplified purification and may be co-expressed with calcineurin B to reconstitute active holoenzyme complexes.
In drug discovery, PPP3CA recombinant protein serves as a target for screening inhibitors to treat autoimmune diseases or conditions involving calcineurin hyperactivity. It also aids in structural studies (e.g., X-ray crystallography) to elucidate binding sites and catalytic mechanisms. Additionally, it is employed in cellular assays to model PPP3CA-related dysfunction or validate genetic findings in transgenic organisms.
Overall, PPP3CA recombinant protein is a critical tool for dissecting calcineurin biology and advancing therapies targeting this versatile phosphatase.
