CC   -!- FUNCTION: Structural component of the T=16 icosahedral capsid. The
CC       capsid is composed of pentamers and hexamers of major capsid
CC       protein/MCP, which are linked together by heterotrimers called
CC       triplexes. These triplexes are formed by a single molecule of triplex
CC       protein 1/TRX1 and two copies of triplex protein 2/TRX2. Additionally,
CC       TRX1 is required for efficient transport of TRX2 to the nucleus, which
CC       is the site of capsid assembly. {ECO:0000255|HAMAP-Rule:MF_04018}.
CC   -!- SUBUNIT: Interacts with TRX2, MCP and capsid vertex component 2/CVC2.
CC       {ECO:0000255|HAMAP-Rule:MF_04018}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000255|HAMAP-Rule:MF_04018}. Host
CC       nucleus {ECO:0000255|HAMAP-Rule:MF_04018}.
CC   -!- SIMILARITY: Belongs to the herpesviridae TRX1 protein family.
CC       {ECO:0000255|HAMAP-Rule:MF_04018}.
