**Background of BRD1 Recombinant Protein**
BRD1 (Bromodomain-containing protein 1) is a chromatin-associated protein belonging to the bromodomain family, which recognizes acetylated lysine residues on histones and non-histone proteins. This interaction enables BRD1 to play a role in epigenetic regulation, particularly in modulating chromatin structure and gene expression. BRD1 is implicated in diverse cellular processes, including transcriptional activation, DNA repair, and cell cycle progression. Dysregulation of BRD1 has been linked to neurodevelopmental disorders, such as schizophrenia, and cancers, where it may act as an oncogene or tumor suppressor depending on context.
Recombinant BRD1 protein is produced using genetic engineering techniques, often in bacterial or mammalian expression systems, to ensure high purity and activity. This engineered protein typically retains functional bromodomains, enabling researchers to study its binding affinity for acetylated substrates, its role in epigenetic complexes (e.g., with histone acetyltransferases or chromatin remodelers), and its interaction with potential therapeutic inhibitors.
Studies leveraging BRD1 recombinant protein have advanced understanding of its structural biology, including crystallographic analyses of bromodomain-acetyl-lysine interactions. Additionally, it serves as a tool for drug discovery, particularly in targeting bromodomains for cancer therapy or neuropsychiatric disease modulation. Its involvement in pathways like Wnt/β-catenin and p53 further highlights its relevance in disease mechanisms.
Overall, BRD1 recombinant protein is a critical reagent for dissecting epigenetic regulation and exploring therapeutic strategies in disorders tied to chromatin dysregulation.
