Pathways for viral entry of the has Figure 5.|7 Stepwise uncoating of adenovirus. (A) Adenoviruses bind the cell receptor via the fiber protein. Interaction of the penton base with an integrin receptor leads to internalization by endocytosis. Low pH in the endosome causes destabilization of the capsid and release of protein VI. The hydrophobic N terminus of protein VI disrupts the endosome membrane, leading to release of a subviral particle into the cytoplasm. The capsid is transported in the cytoplasm along microtubules and docks onto the nuclear pore complex.
