Examples of penton in the following topics:

  • Double-Stranded DNA Viruses: Adenoviruses

    • The virion also has unique "spike" or fiber associated with each penton base of the capsid that aids in attachment to the host cell via host cell surface receptors .
    • Next, a specialized motif in the penton base protein interacts with αv integrin, stimulating internalization of the adenovirus via clathrin-coated pits, resulting in entry of the virion into the host cell within an endosome.
    • These changes, as well as the toxic nature of the pentons, result in the release of the virion into the cytoplasm.

    • The virion also has a unique "spike" or fiber associated with each penton base of the capsid that aids in attachment to the host cell via the receptor on the surface of the host cell.
