CC   -!- FUNCTION: Capsid vertex-specific component that plays a role during
CC       viral DNA encapsidation, assuring correct genome cleavage and
CC       presumably stabilizing capsids that contain full-length viral genomes.
CC       Participates in the interaction between the capsid and the tegument
CC       through interaction with the large tegument protein/LTP.
CC       {ECO:0000255|HAMAP-Rule:MF_04025}.
CC   -!- SUBUNIT: Heterodimerizes with CVC1. Interacts with major capsid
CC       protein/MCP and triplex capsid protein 1/TRX1 at the pentamer vertices.
CC       Interacts with the large tegument protein/LTP. {ECO:0000255|HAMAP-
CC       Rule:MF_04025}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04025}. Host
CC       nucleus {ECO:0000255|HAMAP-Rule:MF_04025}.
CC   -!- SIMILARITY: Belongs to the herpesviridae CVC2 protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04025}.
