RX PubMed=10889190; DOI=10.1074/jbc.M001444200; RA Baudoux L., Defechereux P., Rentier B., Piette J.; RT "Gene activation by Varicella-zoster virus IE4 protein requires its RT dimerization and involves both the arginine-rich sequence, the central RT part, and the carboxyl-terminal cysteine-rich region."; RL J. Biol. Chem. 275:32822-32831(2000). CC -!- FUNCTION: Immediate early (EI) protein that transactivates the CC expression of certain immediate-early, early and late viral genes. CC Acts in concert with IE62 transcriptional transactivator. CC -!- SUBUNIT: Homodimer. Homodimerization is required for CC transactivation. Interacts with IE62; this interaction enhances CC IE62 transactivation. CC -!- SUBCELLULAR LOCATION: Host cytoplasm (By similarity). Host nucleus CC (By similarity). Note=Shuttle between the nucleus and the CC cytoplasm (Probable). IE4 utilizes, at least, XPO1/CRM1 as a CC cofactor for nuclear export. CC -!- SIMILARITY: Belongs to the herpesviridae ICP27 protein family.
