Calcineurin (Ppp3Ca) is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Calcineurin is a calcium/calmodulin-dependent serine/threonine protein phosphatase that plays a critical role in cellular signal transduction, particularly in neurons where it regulates synaptic plasticity, gene transcription, and neuronal survival. It is one of the few known serine/threonine phosphatases that requires calcium/calmodulin for activation, making it a key mediator of calcium-dependent signaling pathways in the nervous system[1][2].
Calcalcineurin is a heterodimer composed of:
The enzyme contains:
Calcineurin plays a central role in regulating synaptic plasticity, a cellular basis for learning and memory:
Calcineurin dephosphorylates transcription factors including:
Calcineurin is hyperactivated in Alzheimer's disease and contributes to pathogenesis:
Calcineurin is a potential therapeutic target for neurodegenerative diseases:
