The ORF22 encodes for the inner tegument protein UL36 that plays multiple roles in the viral cycle. During viral entry it remains associated with the capsid, participates in the capsid transport toward the host nucleus and by interacting with the nuclear pore complex (NPC) faciliate release of viral DNA from the nucleocapsids. Within the host nucleus, acts as a deneddylase and promotes the degradation of nuclear CRLs (cullin-RING ubiquitin ligases) and thereby stabilizes nuclear CRL substrates, while cytoplasmic CRLs remain unaffected. These modifications prevent host cell cycle S-phase progression and create a favourable environment allowing efficient viral genome replication. During viral maturation plays a linker role in association of the outer viral tegument to the capsids together with the inner tegument protein. Our anti-VZV ORF 22 antibody VZ 22.3.10 (described in J Virol. 2013 Jun;87(12):6943-54.) works in ELISA (on immunogen), IF (on VZV infected cells) and each LOT is validated for Western blot (of VZV infected cell lysates) where it specifically recognizes a protein species of ~306 kDa in lysates obtained from VZV infected cells.
