Homodimer (PubMed:10675342). Isoform 1 interacts with HCFC1; the interaction is required to stimulate CREB3 transcriptional activity (PubMed:9271389, PubMed:9389645, PubMed:10629049, PubMed:10984507). Isoform 1 interacts with CREBZF; the interaction occurs only in combination with HCFC1 (PubMed:15705566). Isoform 1 interacts (via central part and transmembrane region) with DCSTAMP (via C-terminus cytoplasmic domain) (PubMed:20546900). Isoform 1 interacts with OS9 (PubMed:20546900). Isoform 1 interacts (via leucine-zipper domain) with CREBRF (via leucine-zipper domain); the interaction occurs only after CREB3 activation and promotes CREB3 degradation (PubMed:18391022). Isoform 1 interacts (via C-terminal domain) with CCR1 (PubMed:15001559). (Microbial infection) Interacts with the HCV core protein; homodimerization is prevented by the HCV core protein (PubMed:10675342). Isoform 1 interacts (via leucine-zipper and transmembrane domains) with HIV-1 TMgp41 (via cytoplasmic domain); the interaction reduces CREB3 stability (PubMed:17054986). Processed cyclic AMP-responsive element-binding protein 3 interacts with HIV-1 Tat (PubMed:17054986).
