Description
Recombinant full-length human BRD3 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. The BRD3 gene accession number is NM_007371.
As the best characterized binding motif for lysine acetylation, Bromodomains (BRDs) are 110 amino acid highly conserved modules found in transcriptional co-regulators, chromatin modifying enzymes and nuclear scaffold proteins. Initially identified in the protein encoded by the D. melanogaster brahama gene. Along with BRD2, BRD4 and BRDT, Bromodomain-containing protein 3 (BRD3) lacks intrinsic chromatin modifying potential and primarily function as scaffolds for transcription factors or other chromatin regulating factors. It is characterized by the presence of two distinct BRDs at the N-terminal end of the protein. BRD3 is involved in the pathognomonic chromosomal translocations seen in NUT midline carcinoma (NMC)
