Human Neurogranin ELISA Standard Curve. Recombinant Human Neurogranin protein was serially diluted 2-fold and captured by Mouse Anti-Human Neurogranin Monoclonal Antibody (Catalog # MAB79473) coated on a Clear Polystyrene Microplate (Catalog # DY990). Sheep Anti-Human/Mouse/Rat Neurogranin Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7947) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: Neurogranin

NRGN (Neurogranin/Ng; also known as RC3, p17 and BICKS) is a member of the neurogranin family of proteins. Although its predicted MW is 7.5 kDa, it runs anomalously at 15-19 kDa in SDS-PAGE. This is apparently due to the adoption of a rigid alpha -helical structure in a negatively charged medium. NRGN has limited expression, being found principally in excitatory neurons of the telencephalon, Golgi and Purkinje cells of the cerebellum, and platelets plus B and T cells in non-nervous tissue. Intracellularly, NRGN is found associated with membranes of the ER, Golgi and mitochondria. This association is often in the form of aggregates (or granules), thus giving rise to its name ("neuro-granules"). NRGN is also found in the nucleus and associated with the postsynaptic spines of dendrites. The principal function of NRGN appears to be the binding, sequestration and concentration of CaM (Calmodulin; a Ca-binding protein) in dendritic spines. Following NMDAR activation, Ca diffuses into the synaptic area, resulting in 1) the simply dissociation of CaM from NRGN, or 2) the phosphorylation of NRGN followed by its dissociation fro CaM. In either case, the freed CaM is now available to activate multiple downstream signaling pathways, some involved in LTP (or memory). Human NRGN is 78 amino acids (aa) in length. It contains one IQ domain (aa 26-47) that binds CaM, and a collagen-like region at the C-terminus (aa 48-78). Regulatory phosphorylation occurs on Ser36, and the N-terminal Met is acetylated. Full-length human NRGN shares 96% aa sequence identity with both mouse and rat NRGN.
