HMG20B, also known as BRAF35-homologous protein (BRAF35HP) or SOX-interacting protein, is a member of the high-mobility group (HMG) protein family. These proteins are characterized by their ability to bind DNA and regulate chromatin structure, transcription, and epigenetic modifications. HMG20B specifically contains an HMG-box domain, which facilitates interactions with DNA and other proteins. Initially identified as a partner of the SOX transcription factors, it plays a critical role in neurogenesis, neural differentiation, and cell fate determination. Studies highlight its involvement in chromatin remodeling complexes, such as the LSD1/CoREST complex, where it contributes to gene silencing by modulating histone modifications. Dysregulation of HMG20B has been linked to neurodevelopmental disorders and cancers, including gliomas and neuroblastoma, emphasizing its importance in maintaining cellular identity and suppressing tumorigenesis.
Recombinant HMG20B protein is engineered using expression systems like *E. coli* or mammalian cells, enabling large-scale production for functional studies. Purified recombinant HMG20B retains DNA-binding activity and facilitates in vitro assays to explore its interactions with transcriptional regulators, chromatin modifiers, or specific DNA sequences. Researchers utilize this protein to investigate its role in epigenetic regulation, neural development, and disease mechanisms. For example, it has been employed to study how HMG20B cooperates with SOX proteins to activate or repress target genes during neuronal differentiation. Additionally, recombinant HMG20B serves as a tool for screening potential therapeutic agents targeting epigenetic pathways in cancer. Its application extends to structural studies, such as crystallography, to resolve molecular mechanisms underlying its biological functions. Overall, recombinant HMG20B is a valuable resource for deciphering the multifaceted roles of this protein in health and disease.
