Function
function
Hexon-linking protein-C: Structural component of the virion that acts as a cement protein on the capsid interior and which glue the peripentonal hexons and group-of-nine hexons together.
Hexon-linking protein-N: Structural component of the virion that acts as a cement protein on the capsid interior and which glue the peripentonal hexons and group-of-nine hexons together.
Miscellaneous
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.

Post-translational modification
Cleaved by the viral protease during virion maturation. May cause the middle segment to be shed from the capsid.

Interaction
Subunit
Interacts with the peripentonal hexons as well as the hexons in the facets. Part of a complex composed of the core-capsid bridging protein, the endosome lysis protein VI and the hexon-linking protein VIII; these interactions bridge the virus core to the capsid.
