Description
Neurogranin is a calmodulin-binding protein expressed exclusively in the brain, particularly in dendritic spines, and participating in the protein kinase C signaling pathway. Neurogranin is the main postsynaptic protein regulating the availability of calmodulin, binding to it in the absence of calcium. Phosphorylation by protein kinase C lowers its binding ability.
Neurogranin is downregulate in Schizophrenia and is not found in the dendrites in patients with Alzheimer disease
