SETDB1-TTD-IN-1(Cat No.:I045266)is a selective inhibitor targeting the Tudor tandem domain (TTD) of SETDB1, a histone methyltransferase responsible for trimethylating histone H3 lysine 9 (H3K9me3), a key epigenetic mark associated with transcriptional repression and heterochromatin formation. By disrupting TTD-mediated recognition of methylated histones, SETDB1-TTD-IN-1 interferes with SETDB1’s chromatin recruitment and gene-silencing functions. This compound is valuable for studying SETDB1’s role in epigenetic regulation, cancer progression, and neurological disorders. Its potency and specificity make it a powerful research tool for probing chromatin biology and developing SETDB1-targeted therapeutic strategies in oncology and beyond.
