Product Science Overview
Protein Phosphatase 3, also known as Calcineurin, is a calcium and calmodulin-dependent serine/threonine protein phosphatase. The alpha isozyme of the catalytic subunit of this enzyme is encoded by the PPP3CA gene. This enzyme plays a crucial role in various biological processes, including T-cell activation, synaptic vesicle recycling, and other calcium-mediated signaling pathways .
Calcineurin is a heterodimer composed of a catalytic subunit (Calcineurin A) and a regulatory subunit (Calcineurin B). The catalytic subunit, encoded by the PPP3CA gene, contains several functional domains, including a calmodulin-binding domain, an autoinhibitory domain, and a catalytic domain. The enzyme is activated by the binding of calcium ions and calmodulin, which induces a conformational change that relieves autoinhibition and allows substrate access to the catalytic site .
Calcineurin plays a pivotal role in the immune system by activating T-cells through the dephosphorylation of the nuclear factor of activated T-cells (NFAT). This process is essential for the transcription of interleukin-2 and other cytokines, which are critical for T-cell proliferation and differentiation . Additionally, Calcineurin is involved in synaptic plasticity and memory formation in the brain, making it a key player in neurobiology .
The mouse anti-human PPP3CA antibody is a monoclonal antibody that specifically targets the alpha isozyme of the catalytic subunit of Calcineurin. This antibody is commonly used in research to study the expression, localization, and function of Calcineurin in various tissues and cell types. It is particularly useful in techniques such as Western blotting, immunohistochemistry, and immunoprecipitation .
- Western Blotting: The mouse anti-human PPP3CA antibody is used to detect the presence and quantify the levels of Calcineurin A alpha in cell and tissue lysates. This technique helps in understanding the protein’s expression patterns under different physiological and pathological conditions .
- Immunohistochemistry: This antibody is employed to visualize the localization of Calcineurin A alpha within tissues. It aids in studying the distribution of the protein in various organs and its changes in disease states .
- Immunoprecipitation: Researchers use this antibody to isolate Calcineurin A alpha from cell extracts, allowing for the study of its interactions with other proteins and its role in signaling pathways .
