Product Overview

CtBP1 (C-terminal binding protein 1) was first recognized as a cellular factor that interacts with the C-terminal portion of adenovirus E1A, a protein involved in the transcriptional regulation of key cellular genes. CtBP1 is able to regulate gene activity through its intrinsic dehydrogenase activity and by interacting with Polycomb Group (PcG) proteins during development. Along with its homologue, CtBP2, it acts as a transcriptional corepressor of zinc-finger homeodomain factor deltaEF1 to regulate a wide range of cellular processes through transrepression mechanisms. Through its direct interaction with PRDM16, CtBP1 has been shown to be involved in brown adipose tissue differentiation by mediating the repression of white fat genes and directing differentiation toward the brown fat gene program. CtBP1 also plays a role in lipid metabolic pathways and membrane fission by regulating the fission machinery operating Golgi tubular networks. CtBP1 has recently been shown to repress transcription of BRCA1 via a redox regulated mechanism. Furthermore, it is thought that downregulation of BRCA1 and E-cadherin in invasive ductal breast carcinoma correlates directly with activation of CtBP1.

Application Description
The product I used is EpiQuick Chromatin Immunoprecipitation (ChiP) Kit (P-2002), and CtBP1 antibody (A-2705). I used this for a Chip assay to examine genes that bind with CtBP1 protein. The antibody works good with human cells on CHiP assay.
