Neurogranin (RC3) is a postsynaptic calmodulin-binding protein enriched in [dendritic spines](/mechanisms/dendritic-spines) of forebrain [neurons](/entities/neurons). It plays a critical role in synaptic plasticity, learning, and memory by regulating calmodulin availability and downstream signaling. Neurogranin has emerged as a promising biomarker for synaptic dysfunction in Alzheimer's disease (AD), Parkinson's disease (PD), and other neurodegenerative disorders.
Neurogranin is a small, intrinsically disordered protein characterized by:
Neurogranin is essential for synaptic plasticity through:
Neurogranin expression is brain-specific, with highest levels in the [hippocampus](/brain-regions/hippocampus), [cortex](/brain-regions/cortex), and striatum.
Neurogranin is deeply involved in AD pathogenesis:
In PD, neurogranin:
Neurogranin integrates multiple synaptic signaling cascades:
Neurogranin is one of the most promising synaptic biomarkers:
