CC -!- FUNCTION: Plays an essential role in virion nuclear egress, the first
CC step of virion release from infected cell. Within the host nucleus,
CC NEC1 interacts with the newly formed capsid through the vertexes and
CC directs it to the inner nuclear membrane by associating with NEC2.
CC Induces the budding of the capsid at the inner nuclear membrane as well
CC as its envelopment into the perinuclear space. There, the NEC1/NEC2
CC complex promotes the fusion of the enveloped capsid with the outer
CC nuclear membrane and the subsequent release of the viral capsid into
CC the cytoplasm where it will reach the secondary budding sites in the
CC host Golgi or trans-Golgi network. {ECO:0000255|HAMAP-Rule:MF_04024,
CC ECO:0000269|PubMed:23365436, ECO:0000269|PubMed:23623980}.
CC -!- SUBUNIT: Forms a heterohexameric complex with NEC1. {ECO:0000255|HAMAP-
CC Rule:MF_04024}.
CC -!- SUBCELLULAR LOCATION: Host nucleus inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_04024, ECO:0000269|PubMed:23365436,
CC ECO:0000269|PubMed:23623980}; Single-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04024, ECO:0000269|PubMed:23365436,
CC ECO:0000269|PubMed:23623980}. Note=Localizes also at the transient
CC membrane of perinuclear virions. {ECO:0000255|HAMAP-Rule:MF_04024}.
CC -!- PTM: Phosphorylated. {ECO:0000255|HAMAP-Rule:MF_04024}.
CC -!- SIMILARITY: Belongs to the herpesviridae NEC2 protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04024}.
