Description: C-terminal-binding protein 1 is encoded by the CTBP1 gene. It binds to the C-terminus of adenovirus E1A proteins. It is a transcriptional repressor(corepressor) and may play a role during cellular proliferation. This protein and the product of a second closely related gene, CTBP2, can dimerize. CtBP1 and CtBP2 preferentially associate with the E1A via a 5 amino acid motif, PLDLS, to repress E1A induced oncogenesis and cellular transformation. CtBP1 is expressed from embryo to adult, but CtBP2 is mainly expressed during embryogenesis. During skeletal and T cell development, CtBP1 and -2 associate with the PLDLSL domain of delta EF1, a cellular zinc finger-homeodomain protein, and thereby enhances delta EF1-induced transcriptional silencing. In addition, CtBP complexes with CtIP, a 125 kDa protein that recognizes distinctly different protein motifs from CtBP. CtIP binds to the BRCT repeats within the breast cancer gene BRCA1 and enables CtBP to influence BRCA1 activity. Both proteins can also interact with a polycomb group protein complex which participates in regulation of gene expression during development. Alternative splicing of transcripts from this gene results in multiple transcript variants.
Immunogen: Amino acids 425-440 (QTVKPEADRDHASDQL-human) were used as the immunogen for this CtBP1 antibody.
Storage: After reconstitution, the CtBP1 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20 °C. Avoid repeated freezing and thawing.
