Comments
  • FUNCTION: Forms the icosaedric capsid of the virus protecting the viral genome. This capsid is composed of 360 VP1, assembled in 72 pentamers. Each pentamer are linked via the C-terminal end of VP1 (By similarity).
  • SUBUNIT: The virus capsid is composed of 75 icosahedral units, each of which is composed of five disulfide-linked copies of VP1 (By similarity).
  • SUBCELLULAR LOCATION: Virion. Nucleus (By similarity).
  • ALTERNATIVE PRODUCTS: 4 named isoforms [FASTA] produced by alternative splicing and alternative initiation.
    NameVP1
    Isoform IDP14996-1
    This is the isoform sequence displayed in this entry.
    NameVP2
    Isoform IDP14997-1
    This isoform is stored in UniProtKB/Swiss-Prot entry P14997.
    NameVP3
    Isoform IDP14997-2
    Note: Produced by alternative initiation at Met-120 of isoform VP2.
    This isoform is stored in UniProtKB/Swiss-Prot entry P14997.
    NameAgno
    Isoform IDP14998-1
    Note: Produced by alternative initiation of isoform VP1 and VP2.
    This isoform is stored in UniProtKB/Swiss-Prot entry P14998.
  • DOMAIN: The intrinsically disordered C-terminal region interacts with neighboring pentamers. The unstructured nature of this region allows to make different interactions depending on the stuctural context: pentamers present at the 12 icosahedral fivefold axes bind five pentamers, when pentamers present at the 60 icosahedral six-fold axes interacts with six pentamers (By similarity).
  • SIMILARITY: Belongs to the polyomaviruses coat protein VP1 family.
