Abstract

Background: C-terminal binding protein 1 (CtBP1) assembles into a tetrameric transcriptional co-repressor but how it directs gene expression is not clear. Results: CtBP1 requires NAD(H) for transition into multimers. Its biochemical activities are separable from transcriptional repression. Conclusion: Tryptophan 318 permits CtBP1 to first dimerize and then tetramerize after the binding of NAD(H). Significance: Clarification of how CtBP1 tetramerizes will permit development of CtBP inhibitors to target oncogenesis.
