UniProtKB - P36849 (CAPSH_ADE03)
Hexon protein
L3
Functioni
Major capsid protein that self-associates to form 240 hexon trimers, each in the shape of a hexagon, building most of the pseudo T=25 capsid. Assembled into trimeric units with the help of the chaperone shutoff protein. Transported by pre-protein VI to the nucleus where it associates with other structural proteins to form an empty capsid. Might be involved, through its interaction with host dyneins, in the intracellular microtubule-dependent transport of incoming viral capsid to the nucleus.

Subunit structurei
Homotrimer.
Interacts with the capsid vertex protein; this interaction binds the peripentonal hexons to the neighboring penton base.
Interacts with the hexon-linking protein; this interaction tethers the hexons surrounding the penton to those situated in the central plate of the facet.
Interacts with the hexon-interlacing protein; this interaction lashes the hexons together.
Interacts with host dyneins DYNC1LI1 and DYNC1I2; this interaction might be involved in intracellular microtubule-dependent transport of incoming viral capsid.
Interacts with the shutoff protein; this interaction allows folding and formation of hexons trimers.
Interacts with pre-protein VI; this interaction probably allows nuclear import of hexon trimers and possibly pre-capsid assembly.
