CC   -!- FUNCTION: Large tegument protein that plays multiple roles in the viral
CC       cycle. During viral entry, remains associated with the capsid while
CC       most of the tegument is detached and participates in the capsid
CC       transport toward the host nucleus. Plays a role in the routing of the
CC       capsid at the nuclear pore complex and subsequent uncoating. Within the
CC       host nucleus, acts as a deneddylase and promotes the degradation of
CC       nuclear CRLs (cullin-RING ubiquitin ligases) and thereby stabilizes
CC       nuclear CRL substrates, while cytoplasmic CRLs remain unaffected. These
CC       modifications prevent host cell cycle S-phase progression and create a
CC       favorable environment allowing efficient viral genome replication.
CC       Participates later in the secondary envelopment of capsids. Indeed,
CC       plays a linker role for the association of the outer viral tegument to
CC       the capsids together with the inner tegument protein.
CC       {ECO:0000255|HAMAP-Rule:MF_04044, ECO:0000269|PubMed:19640989}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Thiol-dependent hydrolysis of ester, thioester, amide, peptide
CC         and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-
CC         residue protein attached to proteins as an intracellular targeting
CC         signal).; EC=3.4.19.12; Evidence={ECO:0000255|HAMAP-Rule:MF_04044};
CC   -!- SUBUNIT: Interacts with host CUL1 and CUL4A; these interactions inhibit
CC       the E3 ligase activity of cullins. Interacts with inner tegument
CC       protein. Interacts with capsid vertex specific component CVC2.
CC       Interacts with the major capsid protein/MCP. {ECO:0000255|HAMAP-
CC       Rule:MF_04044}.
CC   -!- SUBCELLULAR LOCATION: Virion tegument {ECO:0000255|HAMAP-
CC       Rule:MF_04044}. Host cytoplasm {ECO:0000255|HAMAP-Rule:MF_04044}. Host
CC       nucleus {ECO:0000255|HAMAP-Rule:MF_04044}. Note=Tightly associated with
CC       the capsid. {ECO:0000255|HAMAP-Rule:MF_04044}.
CC   -!- SIMILARITY: Belongs to the herpesviridae large tegument protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04044}.
