C-terminal binding protein 1 / brefeldin A (BFA)-dependent ADP-ribosylation substrate (CtBP1/BARS) is a highly conserved transcriptional corepressor, that plays a critical role in regulating gene expression patterns throughout development and in oncogenesis. CtBP regulates target gene transcription, in part, via recruitment of histone deacetylases involved in gene silencing and may act to coordonate histone modifications that regulate gene expression.


The polyclonal antibody reacts with CtBP1, a 49 kDa transcriptional corepressor, that plays a critical role in regulating gene expression.
