The hng ELISA kits listed below are analytical tools for measuring concentrations of hng in various samples. hng is an alternative name for the human NRGN gene, which encodes the protein, neurogranin. It has been mentioned that hng plays a role in nervous system development and signal transduction pathways, among other functions. Structurally, the NRGN protein is described to be 78 amino acid residues in length and 7.6 kilodaltons in mass. This protein is known to be phosphorylated. Other names for this target antigen include RC3 and calmodulin-binding protein.
