CALN1 (Calcineurin 1), also known as protein phosphatase 3 catalytic subunit alpha, is a calcium/calmodulin-dependent serine/threonine phosphatase involved in diverse cellular processes, including signal transduction, immune response, and neuronal development. It functions by dephosphorylating target proteins, thereby regulating critical pathways such as the NFAT (nuclear factor of activated T-cells) signaling cascade. Dysregulation of CALN1 has been implicated in neurological disorders, cardiovascular diseases, and immune dysfunction, making it a subject of interest in both basic and clinical research.
Recombinant CALN1 protein is engineered using molecular cloning techniques, typically expressed in bacterial (e.g., *E. coli*) or eukaryotic systems (e.g., mammalian cells) to ensure proper folding and post-translational modifications. The recombinant form retains the enzymatic activity of native CALN1. enabling in vitro studies to dissect its molecular mechanisms, substrate specificity, and interaction partners. Researchers utilize it to explore calcium-mediated signaling dynamics, screen for inhibitors or activators, and model disease-related mutations.
Purified recombinant CALN1 is often fused with tags (e.g., GST, His-tag) for simplified detection and purification. Its applications span structural biology (e.g., crystallography), drug discovery, and functional assays to study synaptic plasticity, T-cell activation, or cardiomyocyte hypertrophy. Recent studies also investigate its role in cancer progression and neurodegenerative conditions like Alzheimer’s disease. By providing a controlled, scalable source of active protein, recombinant CALN1 accelerates mechanistic insights and therapeutic development targeting calcium-dependent pathways.
