General annotation (Comments)
Structural component of the virion that is likely to participate in vertex stabilization and genome packaging. Stabilizes vertices by tethering the penton bases to neighboring peripentonal hexons. Lashes peripentonal hexons to the neighboring hexons thanks to its interaction with hexon-linking protein. As the virus enters the host cell, capsid vertex proteins are shed concomitant with virion acidification in the endosome. During virus assembly, seems to play a role in packaging of viral DNA via its interaction with packaging protein 3. Ref.5 Ref.7
Interacts with penton and hexon proteins; this interaction binds the penton base to neighboring peripentonal hexons. Interacts with hexon-linking protein; this interaction tethers the peripentonal hexons to hexons situated in the facet. Interacts with packaging protein 3; this interaction is required to promote correct genome packaging. Interacts with adjacent capsid vertex proteins (self-interaction). Ref.5 Ref.7
Expressed in the late phase of the viral replicative cycle.
Cleaved near the N-terminus by the viral protease during virion maturation to form the mature protein By similarity.
All late proteins expressed from the major late promoter are produced by alternative splicing and alternative polyadenylation of the same gene giving rise to non-overlapping ORFs. A leader sequence is present in the N-terminus of all these mRNAs and is recognized by the viral shutoff protein to provide expression although conventional translation via ribosome scanning from the cap has been shut off in the host cell.
Belongs to the adenoviridae capsid vertex protein family.
