Abstract

- CREB3L2 was first identified as the 3'-partner of FUS in a fusion gene that seems to be specific for low grade fibromyxoid sarcoma. In silico analyses suggest that the predicted CREB3L2 protein is a member of the CREB3 family of transcription factors, with its bZIP domain being highly similar to that in CREB3L1, CREB3L3, CREB3L4, CREB3, and Drosophila Bbf-2. In the present study, the authors assessed various cellular outcomes after transfection of NIH3T3 and HEK-293 cells with constructs containing full-length and truncated versions of CREB3L2 and FUS/CREB3L2. Northern blot of CREB3L2 mRNA revealed a 7.4 kbp band that contains 0.4 kbp and 5.5 kbp untranslated 5' and 3' regions, respectively. CREB3L2 constructs containing the first 120 amino acids (aa) showed the highest transcriptional activation. Much stronger transcriptional activation was consistently seen for the FUS/CREB3L2 constructs than for the corresponding CREB3L2 constructs. Transcriptional activity was achieved through the box-B element, ATF6 and CRE binding sites, as well as the GRP78 promoter. Proteins encoded by full-length CREB3L2 and FUS/CREB3L2 were localized to reticular structures of the cytoplasm, whereas the corresponding, truncated proteins lacking the transmembrane domain and the carboxy-terminal part of CREB3L2 resided within the nucleus. The results of the present study show that CREB3L2 is not only structurally, but also functionally very similar to CREB3L1. Thus, studies regarding the pathways influenced by wild-type CREB3L2 should provide valuable clues to the pathogenetic significance of the FUS/CREB3L2 chimera in low grade fibromyxoid sarcoma.
