CtBPs mediate repression of genes controlling proliferation, apoptosis, adhesion, and invasiveness via PxDLS motif-dependent binding. Despite structural similarity to 2-hydroxyacid dehydrogenases, CtBPs exhibit unique nuclear and cytoplasmic roles, including Golgi fission and synaptic ribbon formation. While isoforms share overlapping expression and co-repressor complex membership, knockout studies reveal distinct developmental functions. This work explores CtBP biology, emphasizing their dual roles, protein interactions, and implications for transcriptional regulation and tumorigenesis.}, url = {http://digitalcollections.ohsu.edu/record/639}, doi = {https://doi.org/10.6083/M498851X}, }
