HCV-P7 (Clarke et al., 2006). It's mechanism and function have been investigated in considerable detail (Gan et al. 2014). Histidine-17, which faces the lumen of the pore when protonated, allows Cl- entry, but deprotonation also allows Ca2+ entry. Imposition of voltage creates a Cl- current (Wang et al. 2014). The structure and dual pore/ion channel activity of p7 of different HCV genotypes have been reviewed (Madan and Bartenschlager 2015). It may transport protons; it's structure has been determined by NMR (Montserret et al. 2010) and by electron microscopy (Luik et al. 2009). The p7 N-terminal helical region is critical for
E2/p7 processing, protein-protein interactions, ion channel activity, and infectious HCV production (Scull et al. 2015).
