Capsid vertex-specific component that plays a role during viral DNA encapsidation, assuring correct genome cleavage and presumably stabilizing capsids that contain full-length viral genomes. Participates in the interaction between the capsid and the tegument through interaction with the large tegument protein/LTP. May mediate the capsid docking to the nuclear pore allowing entry of the viral genome into the host nucleus through binding to host nucleoporins NUP214. Heterodimerizes with CVC1. Interacts with major capsid protein/MCP and triplex capsid protein 1/TRX1 at the pentamer vertices. Interacts with the large tegument protein/LTP. Interacts with host NUP214; this interaction might be essential to the capsid docking to the host nuclear pore. Interacts with host TMEM250. Belongs to the herpesviridae CVC2 protein family.
