CtBP binds NAD and NADH, and the NAD/NADH ratio appears to regulate the interactions of CtBP with DNA-binding transcription factors (6, 7), suggesting a potential role for CtBP… Continue reading Supplementary Materials Supporting Information supp_106_5_1496__index. been proven to exhibit dehydrogenase activity
