• PubMed Abstract: 
  

  The capsid protein (CA) of retroviruses, such as Rous sarcoma virus (RSV), consists of two independently folded domains. CA functions as part of a polyprotein during particle assembly and budding and, in addition, forms a shell encapsidating the genomic RNA in the mature, infectious virus.
