Viral genomic RNA (vRNA) and complementary RNA (cRNA) are likely bound by the influenza nucleoprotein (NP) immediately upon synthesis. Although two nuclear localization signals have been mapped in the NP, an unconventional N-terminal NLS and a bipartite NLS within amino acids 198-216 (Wang, 1997; Neumann, 1997; Ozawa, 2007), the crystal structure of the NP suggests that only the unconventional NLS is exposed and can be used as a functional NLS (Ye, 2006). This unconvenetional NLS interacts with importins alpha-1 and -2 (Cros et al., 2005; Wang et al., 1997; Buolo et al., 2006). The three-dimensional structure of NP has revealed that NP molecules associate as a trimer, interacting through beta-sheets b5, b6, and b7 in the C-terminal domain of the protein; the viral RNA likely wraps around the outside of the complex (Ye, 2006).
