NRGN
Domain
Neurogranin is intrinsically unstructured; however, upon binding with CaM, The IQ domain adopts a helical conformation.
Function
Acts as a 'third messenger' substrate of protein kinase C-mediated molecular cascades during synaptic development and remodeling. Binds to calmodulin in the absence of calcium (By similarity).
Post-translational modifications
Phosphorylated at Ser-36 by PHK and PKC, phosphorylation prevents interaction with Calmodulin and interrupts several learning- and memory-associated functions.
Sequence Similarities
Belongs to the neurogranin family.
Tissue Specificity
In the cerebral cortex, found in the cell bodies of neurons in layers II-VI, and in apical and basal dendrites of pyramidal neurons. Is not found in the dendrites in patients with Alzheimer disease.
Alternative names
Neurogranin, Ng, RC3, NRGN
