Claim: In the list of Rabies Virus ( a neurotropic virus which is a virus that infects nerve cells) ORFs the symbol N refers to Nucleoprotein, which keeps nucleoprotein condensed, and the symbol P refers to Phosphoprotein which involves various regulatory functions.
Evidence: Rabies lyssavirus, formerly Rabies virus, is a neurotropic virus that causes rabies in humans and animals. N Nucleoprotein Coats the RNA. 
Keeps nucleoprotein condensed. Important for assembly; has roles in regulation. Matrix M
