Background Information

C-Terminal binding protein 2 (CTBP2) is a transcriptional repressor. It contains a NAD+ binding domain similar to NAD+-dependent 2-hydroxyacid dehydrogenases. This protein is thought to bind to the C-terminus of the adenovirus E1A proteins. Studies in mice suggested that this protein is involved in transcriptional repression. CTBP2 is expressed in all tissues tested, with a higher level of expression in the heart, skeletal muscle, and pancreas. The gene of CTBP2 is mapped to human chromosome 21q21.3.
