CC   -!- FUNCTION: Tegument protein that plays a role in the inhibition of host
CC       intrinsic defenses to promote viral early gene activation. Interacts
CC       with host DAXX and thereby disrupts the complex between DAXX and ATRX.
CC       Suppresses the DAXX-ATRX dependent deposition of histone H3.3 on viral
CC       chromatin allowing viral transcription. May also play a role in virus
CC       entry at attachment or membrane fusion steps.
CC       {ECO:0000250|UniProtKB:P03179}.
CC   -!- SUBUNIT: Interacts with host DAXX; this interaction disrupts the
CC       chromatin remodeling complex ATRX:DAXX and thus allows viral
CC       transcription. {ECO:0000250|UniProtKB:P03179}.
CC   -!- SUBCELLULAR LOCATION: Virion tegument {ECO:0000250|UniProtKB:P03179}.
CC       Host nucleus {ECO:0000250|UniProtKB:P03179}. Note=Colocalizes with host
CC       DAXX at PML nuclear bodies. {ECO:0000250|UniProtKB:P03179}.
CC   -!- SIMILARITY: Belongs to the herpesviridae MTP family. {ECO:0000305}.
CC   -!- CAUTION: Controvertial experiments have localized MTP at the virion
CC       surface. {ECO:0000305}.
