CC -!- FUNCTION: Structural component of the virion that acts as a cement
CC protein on the capsid exterior and forms triskelion structures
CC consisting of three molecules that stabilize three hexon trimers at the
CC center of each icosahedral facet and fixes the peripentonal hexons.
CC Dispensable for assembly. During virus entry, recruits the anterograde
CC motor kinesin-1 to the capsid docked at the nuclear pore complex
CC thereby subjecting the docked capsid to a pulling force. The resulting
CC tension leads to capsid disruption, dispersion of capsid fragments
CC toward cell periphery and eventually viral DNA entry into the host
CC nucleus. {ECO:0000255|HAMAP-Rule:MF_04050, ECO:0000269|PubMed:20798312,
CC ECO:0000269|PubMed:25071205}.
CC -!- SUBUNIT: Homotrimer. Interacts with hexon protein; this interaction
CC tethers the hexons together (PubMed:20798312, PubMed:25071205). Self-
CC interacts with adjacent proteins (PubMed:20798312, PubMed:25071205).
CC Interacts with kinesin light chain KLC1; this interaction leads to
CC capsid disruption at the nuclear pore complex during virus entry into
CC host cell (By similarity). {ECO:0000250|UniProtKB:P03282,
CC ECO:0000255|HAMAP-Rule:MF_04050, ECO:0000269|PubMed:20798312,
CC ECO:0000269|PubMed:25071205}.
CC -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04050,
CC ECO:0000269|PubMed:20798312, ECO:0000269|PubMed:25071205}. Host nucleus
CC {ECO:0000255|HAMAP-Rule:MF_04050, ECO:0000305|PubMed:20798312}.
CC Note=Located in the canyons between the hexons on the outer surface of
CC the capsid. Forms a sort of hairnet on the outer side of the virion.
CC Present in 240 copies per virion. {ECO:0000255|HAMAP-Rule:MF_04050,
CC ECO:0000269|PubMed:20798312, ECO:0000269|PubMed:25071205}.
CC -!- INDUCTION: Expressed in the intermediate phase of the viral replicative
CC cycle. {ECO:0000255|HAMAP-Rule:MF_04050}.
CC -!- DOMAIN: Three N-terminal domains of hexon-interlacing protein form
CC triskelions between hexon capsomers. {ECO:0000255|HAMAP-Rule:MF_04050,
CC ECO:0000269|PubMed:20798312, ECO:0000269|PubMed:25071205}.
CC -!- MISCELLANEOUS: This protein is only encoded by mastadenoviruses, and
CC may therefore play a role in mammals tropism. {ECO:0000255|HAMAP-
CC Rule:MF_04050}.
CC -!- SIMILARITY: Belongs to the adenoviridae hexon-interlacing protein
CC family. {ECO:0000255|HAMAP-Rule:MF_04050, ECO:0000305}.
