BAZ1B, also known as Bromodomain Adjacent to Zinc Finger Domain 1B or WSTF (Williams syndrome transcription factor), is a multifunctional protein encoded by the *BAZ1B* gene located on human chromosome 7q11.23. It is a key component of the WSTF-ISWI chromatin remodeling complex, which regulates nucleosome spacing, histone modification, and gene expression through ATP-dependent chromatin remodeling. BAZ1B contains a bromodomain, which binds acetylated lysine residues on histones, and a WAC domain involved in protein-protein interactions. Notably, it exhibits tyrosine kinase activity, phosphorylating substrates like histone H2AX, thereby influencing DNA damage response and chromatin dynamics.
BAZ1B plays roles in diverse cellular processes, including cell cycle regulation, DNA repair, and neural development. Its genetic deletion or dysfunction is linked to Williams-Beuren syndrome (WBS), a neurodevelopmental disorder characterized by cardiovascular and cognitive abnormalities, as the *BAZ1B* gene resides within the commonly deleted WBS chromosomal region. Recombinant BAZ1B, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), enables functional studies to dissect its enzymatic activity, chromatin interactions, and pathological mechanisms. It serves as a critical tool for investigating epigenetic regulation, disease pathways, and potential therapeutic targets, particularly in cancers and neurodevelopmental disorders. Research on recombinant BAZ1B continues to uncover its interplay with other chromatin remodelers and its broader impact on cellular homeostasis.
