Description
Neurogranin is a small neuronal protein that binds to calmodulin in the absence of Ca2+. Neurogranin is primarily expressed in the brain and is enriched in somato-dendritic compartments of projection neurons in various regions of the brain. Postsynaptically-enriched neurogranin likely influences Ca2+ or Ca2+/calmodulin-dependent neuronal functions, including synaptic plasticity, by binding to and releasing calmodulin in a Ca2+-dependent manner. Genetic variants in the gene encoding neurogranin, NRGN, are linked to several neuropsychiatric diseases, including schizophrenia
