Publication Abstract from PubMed
C-terminal binding proteins (CtBPs) are multi-functional proteins involved in nuclear transcriptional co-repression, Golgi membrane fission, and synaptic ribbon formation. Binding of NAD(H) to CtBPs promotes dimerization. CtBP dimers act as a scaffold for multimeric protein complex formation, thus bridging transcriptional repressors and their targets in the nucleus. Based on size-exclusion chromatography experiments and on the crystal structure of the NAD(H)-free G172E CtBP mutant, we show here that absence of NAD(H) induces flexibility/backbone conformational changes at the dimerization interface and at the CtBP interdomain region. The results presented shed first light on the correlation between NAD(H)-binding and functional CtBP dimerization.
