This is a synthetic peptide designed for use in combination with anti-Dr1 Antibody. It may block above mentioned antibody from binding to its target protein in western blot and/or immunohistochecmistry under proper experimental settings. There is no guarantee for its use in other applications.
The association of the DR1/DRAP1 heterodimer with TBP results in a functional repression of both activated and basal transcription of class II genes. This interaction precludes the formation of a transcription-competent complex by inhibiting the association of TFIIA and/or TFIIB with TBP. Dr1 can bind to DNA on its own. It is a component of the ATAC complex, a complex with histone acetyltransferase activity on histones H3 and H4.
