CC -!- FUNCTION: [Hexon-linking protein-N]: Structural component of the virion
CC that acts as a cement protein on the capsid interior and which glue the
CC peripentonal hexons and group-of-nine hexons together.
CC {ECO:0000255|HAMAP-Rule:MF_04049}.
CC -!- FUNCTION: [Hexon-linking protein-C]: Structural component of the virion
CC that acts as a cement protein on the capsid interior and which glue the
CC peripentonal hexons and group-of-nine hexons together.
CC {ECO:0000255|HAMAP-Rule:MF_04049}.
CC -!- SUBUNIT: Interacts with the peripentonal hexons as well as the hexons
CC in the facets. Part of a complex composed of the core-capsid bridging
CC protein, the endosome lysis protein VI and the hexon-linking protein
CC VIII; these interactions bridge the virus core to the capsid.
CC {ECO:0000255|HAMAP-Rule:MF_04049}.
CC -!- SUBCELLULAR LOCATION: [Hexon-linking protein-C]: Virion
CC {ECO:0000255|HAMAP-Rule:MF_04049}. Note=Located on the inner side of
CC the capsid shell. Present in 120 copies per virion. {ECO:0000255|HAMAP-
CC Rule:MF_04049}.
CC -!- SUBCELLULAR LOCATION: [Pre-hexon-linking protein VIII]: Host nucleus
CC {ECO:0000255|HAMAP-Rule:MF_04049}.
CC -!- SUBCELLULAR LOCATION: [Hexon-linking protein-N]: Virion
CC {ECO:0000255|HAMAP-Rule:MF_04049}. Note=Located on the inner side of
CC the capsid shell. Present in 120 copies per virion. {ECO:0000255|HAMAP-
CC Rule:MF_04049}.
CC -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC {ECO:0000255|HAMAP-Rule:MF_04049}.
CC -!- PTM: Cleaved by the viral protease during virion maturation. May cause
CC the middle segment to be shed from the capsid. {ECO:0000255|HAMAP-
CC Rule:MF_04049}.
CC -!- MISCELLANEOUS: All late proteins expressed from the major late promoter
CC are produced by alternative splicing and alternative polyadenylation of
CC the same gene giving rise to non-overlapping ORFs. A leader sequence is
CC present in the N-terminus of all these mRNAs and is recognized by the
CC viral shutoff protein to provide expression although conventional
CC translation via ribosome scanning from the cap has been shut off in the
CC host cell. {ECO:0000255|HAMAP-Rule:MF_04049}.
CC -!- SIMILARITY: Belongs to the adenoviridae hexon-linking protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04049, ECO:0000305}.
