== Function ==
[https://www.uniprot.org/uniprot/SCAF_HCMVA SCAF_HCMVA] Capsid scaffolding protein acts as a scaffold protein by binding major capsid protein UL86 in the cytoplasm, inducing the nuclear localization of both proteins. Multimerizes in the nucleus such as protein UL86 forms the icosahedral T=16 capsid. Autocatalytic cleavage releases the assembly protein, and subsequently abolishes interaction with major capsid protein UL86. Cleavages products are evicted from the capsid before or during DNA packaging (By similarity).  Assemblin is a protease essential for virion assembly in the nucleus. Catalyzes the cleavage of the assembly protein after complete capsid formation. Assemblin and cleavages products are evicted from the capsid before or during DNA packaging (By similarity).  Assembly protein plays a major role in capsid assembly. Acts as a scaffold protein by binding major capsid protein UL86. Multimerizes in the nucleus such as protein UL86 forms the icosahedral T=16 capsid. Cleaved by assemblin after capsid completion. The cleavages products are evicted from the capsid before or during DNA packaging (By similarity).
