| + | [[http://www.uniprot.org/uniprot/PRO_ADE02 PRO_ADE02]] Cleaves viral precursor proteins (pTP, pIIIa, pVI, pVII, pVIII, and pX) inside newly assembled particles giving rise to mature virions. Protease complexed to its cofactor slides along the viral DNA to specifically locate and cleave the viral precursors. Mature virions have a weakened organization compared to the unmature virions, thereby facilitating subsequent uncoating. Without maturation, the particle lacks infectivity and is unable to uncoat. Late in adenovirus infection, in the cytoplasm, may participate in the cytoskeleton destruction. Cleaves host cells cytoskeletal keratins K7 and K18.<ref>PMID:22791715</ref> [[http://www.uniprot.org/uniprot/CAP6_ADE02 CAP6_ADE02]] Pre-protein VI: During virus assembly, promotes hexon trimers nuclear import through nuclear pore complexes via an importin alpha/beta-dependent mechanism. By analogy to herpesviruses capsid assembly, might act as a scaffold protein to promote the formation of the icosahedral capsid.<ref>PMID:14633984</ref> <ref>PMID:15681401</ref> <ref>PMID:20333243</ref> <ref>PMID:20409568</ref> <ref>PMID:21209115</ref> <ref>PMID:21843868</ref> Endosome lysis protein: Structural component of the virion that provides increased stability to the particle shell through its interaction with the core-capsid bridging protein. Fibers shedding during virus entry into host cell allows the endosome lysis protein to be exposed as a membrane-lytic peptide. Exhibits pH-independent membrane fragmentation activity and probably mediates viral rapid escape from host endosome via organellar membrane lysis. It is not clear if it then remains partially associated with the capsid and involved in the intracellular microtubule-dependent transport of capsid to the nucleus, or if it is lost during endosomal penetration.<ref>PMID:14633984</ref> <ref>PMID:15681401</ref> <ref>PMID:20333243</ref> <ref>PMID:20409568</ref> <ref>PMID:21209115</ref> <ref>PMID:21843868</ref> Protease cofactor: Cofactor that activates the viral protease.
