Introduction
Protein Dr1, also known as Down-regulator of transcription 1, Negative cofactor 2-beta and TATA-binding protein-associated phosphoprotein, belongs to the NC2 beta/DR1 family. DR1 contains a histone fold motif at the amino terminus, a TBP-binding domain, and a glutamine- and alanine-rich region. DR1 as a TBP associated phosphoprotein that represses both basal and activated levles of transcription. DR1 is an component of the ADA2A-containing complex (ATAC) which posses histone acetyltransferase activity on histone H3 and H4.
BP001164-CE32: Recombinant Human Down-Regulator of Transcription 1 (DR1) Protein
Source: E. coli-derived.
Recombinant Human Protein Dr1 (DR1) Protein is expressed with sequence (Ala2-Ile176) of Human DR1.
Purity: > 95% by SEC-HPLC and reducing SDS-PAGE.
Endotoxin: < 0.1 ng/ug (1 IEU/ug).
Formulation: Lyophilized from a 0.2 um filtered solution of 20 mM Tris-HCl, 150 mM NaCl, 1 mM DTT, pH 8.0.
Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Shipping: The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
