• PubMed Abstract: 
  

  Adenoviral infection begins with the binding of virion to the surface of host cells. Specific attachment is achieved through interactions between host-cell receptors and the adenovirus fiber protein and is mediated by the globular carboxy-terminal domain of the adenovirus fiber protein, termed the carboxy-terminal knob domain.
