背景信息

Calcineurin (CaN), also known as protein phosphatase 3. is a calcium- and calmodulin-dependent serine/threonine phosphatase that plays a pivotal role in cellular signaling pathways. Initially identified in the brain, it is ubiquitously expressed in eukaryotic organisms and consists of a catalytic subunit (CaN A) and a regulatory subunit (CaN B). CaN A contains an autoinhibitory domain that is displaced upon calcium binding to CaN B, which activates the phosphatase. This enzyme is critically involved in T-cell activation via the NFAT (nuclear factor of activated T-cells) pathway, making it a key target for immunosuppressive drugs like cyclosporine A and tacrolimus (FK506).

Recombinant CaN proteins are engineered to study its structure-function relationships, enzymatic activity, and interactions with substrates or inhibitors. Produced using expression systems such as *E. coli* or mammalian cells, recombinant CaN retains calcium/calmodulin-dependent phosphatase activity and is widely utilized in biochemical assays, drug discovery, and structural studies. Mutagenesis approaches help dissect residues critical for catalytic activity or regulatory mechanisms. For instance, truncated forms lacking the autoinhibitory domain exhibit constitutive activity.

In neuroscience, recombinant CaN is employed to explore its roles in synaptic plasticity, memory formation, and neurodegenerative diseases. Its involvement in cardiac hypertrophy and immune disorders further underscores its biomedical relevance. By enabling precise manipulation and large-scale production, recombinant CaN technology accelerates research into its physiological and pathological mechanisms, offering potential therapeutic avenues for conditions linked to dysregulated calcium signaling.
