Calcineurin is a heterodimer of a catalytic A subunit (58-64 kDa) and a calcium-binding B subunit (19 kDa). It contains a calmodulin-binding domain and a catalytic domain. FK506 and cyclosporine bind and inhibit calcineurin.
Calcineurin is calcium/calmodulin-dependent phosphatase that dephosphorylates numerous substrates including NFAT transcription factors, AMPA and NMDA receptor subunits, and tau. It regulates synaptic plasticity, immune response, and gene expression.
Calcineurin dysregulation is implicated in neurodegeneration. In AD, calcineurin activity is altered, affecting tau phosphorylation and synaptic function. In PD, calcineurin may contribute to dopaminergic neuron death. Calcineurin inhibition can be neuroprotective in some contexts.
Calcineurin inhibitors (FK506, cyclosporine) are immunosuppressive but have neuroprotective potential. However, systemic immunosuppression limits use. Novel calcineurin modulators are being explored.
