== 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).

== Publication Abstract from PubMed ==
 +
Human cytomegalovirus (hCMV), a herpesvirus, infects up to 70% of the general population in the United States and can cause morbidity and mortality in immunosuppressed individuals (organ-transplant recipients and AIDS patients) and congenitally infected newborns. hCMV protease is essential for the production of mature infectious virions, as it performs proteolytic processing near the carboxy terminus (M-site) of the viral assembly protein precursor. hCMV protease is a serine protease, although it has little homology to other clans of serine proteases. Here we report the crystal structure of hCMV protease at 2.0 angstroms resolution, and show that it possesses a new polypeptide backbone fold. Ser 132 and His 63 are found in close proximity in the active site, confirming earlier biochemical and mutagenesis studies. The structure suggests that the third member of the triad is probably His 157. A dimer of the protease with an extensive interface is found in the crystal structure. This structure information will help in the design and optimization of inhibitors against herpesvirus proteases.
