Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly112 of human DR1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Down-regulator of transcription 1 (DR1), also known as negative cofactor 2-β (NC2-β), forms a heterodimer with DR1 associated protein 1 (DRAP1)/NC2-α and acts as a negative regulator of RNA polymerase II and III (RNAPII and III) transcription (1-5). DR1 activity is thought to be important for modulating the switch between basal transcription activity and transcription activator driven transcription (2,6,7). DR1 interaction with TATA binding protein (TBP) blocks the association of general transcription factors TFIIA and TFIIB with TBP and disrupts the formation of the RNAPII transcription initiation complex (1,8,9). RNAPIII driven transcription is also inhibited by DR1 interaction with TBP. DR1 disrupts the interaction of TBP with the TFIIB related factor (BRF)/RNAPIII B-related factor, inhibiting transcription initiation by the RNAPIII machinery (4).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
