VZV ORF18 (UniProtKB – Q6QCN7) encodes a small subunit of the viral ribonucleotide reductase, which together with the large subunit, encoded by the VZV ORF19, forms the ribonucleotide reductase holoenzyme complex (RNR) (Curr. Top. Microbiol. Immunol. 342, 1–14 (2010)). RNR acts as a key enzyme that catalyzes the reductive synthesis of deoxyribonucleotides from corresponding ribonucleotides, thus providing precursors for viral DNA replication in non-dividing cells, as well as enabling reactivation of the virus in latently infected cells. VZV ORF18 is an orthologue of HSV1 protein UL40. Kinetics of VZV ORF8 protein expression during lytic infection in vitro was assessed using western blot and our anti-VZV18 antibody VZ 18C.16 and ORF18 were detected between 8 and 10 hpi, typical for proteins involved in viral DNA replication at an early (E) phase of viral infection. Our anti-VZV18 antibody VZ 18C.16 works in ELISA (on immunogen) and each LOT is validated for Western blot of VZV infected cell lysates, where it recognizes a protein of ~36 kDa, which corresponds well to the predicted protein size (described in J Virol. 2013 Jun;87(12):6943-54.).

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.
VZV ORF4 encodes an IE4 protein that acts as transactivator of several immediate early, early and late VZV genes. Dimerization of IE4 is required for its transactivation function.
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.
Immediate-early 62 protein (IE62) is a homolog of herpes simplex type 1 (HSV-1) ICP4. These two proteins have conserved DNA bidnding domain,while not activation domain (J Virol 1993. 67: 4246-4251).
ORF48 encodes an alkaline nuclease (J Virol. 87: 11936-11938). ORF48 protein is homologous to herpes simplex type 1 (HSV-1) UL12, human cytomegalovirus (hCMV) UL98 and Epstein Barr virus (EBV) BGLF5.
