Description: Transcriptional repression is critical for genetic regulation of many cellular proteins, and involves either a transcription regulator that has an intrinsic repressor domain, or a transcription regulator that contains a binding site in the regulatory domain where a co-repressor can bind. C-terminal binding proteins (CtBP1 and CtBP2) are a class of co-repressors that interact with a subset of transcription factors through a PLDLSL sequence motif. CtBP1 and CtBP2 are 80% homologous, and both are expressed at high levels in embryonic tissues. However, CtBP1 is expressed higher in adult tissues, and is more widely expressed in embryonic and adult tissues. Both CtBP1 and CtBP2 bind the deltaEF1 zinc finger-homeodomain transcription factor, and enhance transcriptional repression via interaction with the PLDLSL-sequence in deltaEF1. CtBP1 and CtBP2 bind other zinc finger transcription factors, including Kheper and BKLF. In addition, CtBP2 interacts with other transcription factors, such as hFOG-2, Evi-1, AREB6, and ZEB. Thus, CtBP1 and CtBP2 may be important co-repressors for a variety of transcriptional factors. This antibody is routinely tested by western blot analysis.
