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 δEF1 zinc finger-homeodomain transcription factor, and enhance transcriptional repression via interaction with the PLDLSL-sequence in δEF1.  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. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
