This peptide is a 29 amino acid fragment derived from rabies virus glycoprotein (RVG). Because neurotropic viruses cross the blood-brain barrier to infect brain cells, the same strategy may be used to enter the central nervous system and deliver siRNA to the brain. This peptide specifically binds to the acetylcholine receptor expressed by neuronal cells.
