The ORF50 gene of the varicella-zoster virus (VZV) encodes glycoprotein M which is conserved among all herpesviruses. VZV gM is predicted to be an eight-transmembrane envelope glycoprotein modified with a complex N-linked oligosaccharide.
Open reading frame 37 (ORF37) of Varicella zoster encodes for envelope glycoprotein H (gH). VZV gH is a 118kDa type 1 transmembrane glycoprotein highly conserved among other alphaherpesviruses.
VZV ORF21 encodes a 115 kDa protein that is essential for viral replication in cell culture and is also expressed during, but is not required for establishment of latency in dorsal root and cranial nerve ganglia.
VZV ORF19 encodes a large, N-terminal subunit 1 of the viral ribonucleotide reductase, which together with the small subunit, encoded by the VZV ORF 18, forms the ribonucleotide reductase holoenzyme complex (RNR).
pUL56 is highly conserved 130-kDa DNA binding protein encoded by Human cytomegalovirus (HCMV) gene UL56. It exists as a dimer formed by association of two ring shaped structures connected to each other by a bridge at their base (FEBS Letters (2004) 563, 135-40).
