**Background of BRAP Recombinant Protein**
BRAP (BRCA1-associated protein) is a ubiquitously expressed protein initially identified through its interaction with the tumor suppressor BRCA1. which plays a critical role in DNA repair and genomic stability. Functionally, BRAP acts as a regulatory component in multiple cellular pathways, including the modulation of ubiquitin-proteasome systems and redox signaling. It contains a conserved Zn-finger ubiquitin-binding domain, enabling participation in post-translational modifications and protein degradation processes.
BRAP gained attention due to its role in oxidative stress responses, where it regulates the antioxidant transcription factor Nrf2 by controlling its ubiquitination and degradation. Dysregulation of BRAP has been linked to pathological conditions, such as cancer and cardiovascular diseases. For instance, aberrant BRAP expression may impair cellular defense mechanisms against oxidative damage, contributing to tumorigenesis or atherosclerosis progression.
The recombinant BRAP protein is engineered using expression systems like *E. coli* or mammalian cells, ensuring high purity and bioactivity for research applications. It serves as a vital tool for studying BRAP's molecular interactions, signaling cascades, and its impact on disease mechanisms. Researchers utilize recombinant BRAP in *in vitro* assays, structural studies, and therapeutic target validation, particularly in contexts involving oxidative stress and DNA damage response. Its production enables the development of inhibitors or activators to modulate BRAP-related pathways, offering potential therapeutic strategies for cancers or metabolic disorders. Overall, BRAP recombinant protein bridges fundamental research and translational medicine, enhancing understanding of cellular stress adaptation and disease pathogenesis.
