KAT7 (lysine acetyltransferase 7), also known as HBO1. is a member of the MYST family of histone acetyltransferases (HATs) that plays a critical role in epigenetic regulation. It catalyzes the acetylation of histone H3 on lysine 14 (H3K14), a post-translational modification associated with transcriptional activation and chromatin remodeling. KAT7 functions as part of multi-protein complexes, interacting with factors like ING4/5 and Jade proteins to target specific genomic loci. Its activity is essential for DNA replication, cell cycle progression, and DNA damage repair, linking it to fundamental cellular processes. Dysregulation of KAT7 has been implicated in cancer, aging-related disorders, and metabolic diseases, making it a potential therapeutic target.
Recombinant KAT7 protein is engineered for in vitro studies to dissect its enzymatic mechanisms, substrate specificity, and interactions. Produced via heterologous expression systems (e.g., E. coli or mammalian cells), it retains catalytic activity and structural integrity, enabling biochemical assays, inhibitor screening, and structural analyses. Researchers use it to study how KAT7-mediated acetylation impacts gene expression profiles, cellular differentiation, and senescence. Recent studies highlight its role in somatic cell reprogramming and stem cell maintenance, suggesting broader implications in regenerative medicine. However, challenges remain in stabilizing the protein and mimicking its native chromatin-bound context. Advances in cryo-EM and crystallography using recombinant KAT7 have begun unraveling its 3D architecture, aiding drug design. As interest grows in epigenetic therapies, recombinant KAT7 serves as a vital tool to explore HAT modulation strategies for diseases like hematologic malignancies or age-related degeneration.
