CC   -!- FUNCTION: Plays an essential role in cytoplasmic secondary envelopment
CC       during viral egress. Interacts with the capsid via the large tegument
CC       protein/LTP and participates in its transport to the host trans-Golgi
CC       network (TGN) where secondary envelopment occurs. Modulates
CC       tegumentation and capsid accumulation at the viral assembly complex.
CC       {ECO:0000255|HAMAP-Rule:MF_04043}.
CC   -!- SUBUNIT: Interacts (via C-terminus) with the large tegument protein/LTP
CC       (via N-terminus). {ECO:0000255|HAMAP-Rule:MF_04043}.
CC   -!- SUBCELLULAR LOCATION: Virion tegument {ECO:0000255|HAMAP-
CC       Rule:MF_04043}. Host cytoplasm {ECO:0000255|HAMAP-Rule:MF_04043}. Host
CC       nucleus {ECO:0000255|HAMAP-Rule:MF_04043}. Host Golgi apparatus, host
CC       trans-Golgi network {ECO:0000255|HAMAP-Rule:MF_04043}.
CC   -!- SIMILARITY: Belongs to the herpesviridae inner tegument protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04043}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAA16738.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
