[Encoded by human CREB3 Gene (bZIP/CREB Family), ubiquitous 371-aa cAMP Responsive Element Binding Protein 3 is a conserved transcription factor that binds to octameric DNA palindrome cAMP-response elements (CRE) present in many viral and cellular promoters; possesses an acidic Glu-rich N-terminal transcription activation domain, a Ser-rich region, a central bZIP domain, and a Pro-rich C-terminal region; and interacts with conserved HCFC1 and OCT1. Cytoplasmic CREB3 is colocalized with ER-associated Calnexin. CREB3 and HSV VP16 protein bind the same HCFC1 site. CREB3-HCFC1 release permits VP16-induced transcription of HSV immediate-early genes by association with OCT1, stabilized by interaction with the interacting HCFC1 N- and C-termini. HCV core protein C terminus interacts with the CREB3 bZIP domain and prevents nuclear CREB3 dimer formation. (NCI) ( NCI )]
