BRDT (bromodomain testis-associated) is a BET family chromatin reader that recognizes acetylated lysines on histone tails to regulate transcriptional programs during spermatogenesis and germ cell differentiation. By modulating chromatin accessibility, BRDT influences RNA polymerase II–dependent gene expression, chromatin remodeling, and epigenetic control of meiosis-related pathways. Aberrant regulation of BET proteins, including BRDT, has been associated with altered transcriptional states relevant to cancer biology, where bromodomain-dependent enhancer activity and lineage programs can become dysregulated. As a testis-enriched factor with defined bromodomain-mediated interactions, BRDT is a useful model for studying acetylation-dependent transcriptional regulation and chromatin dynamics.
BRDT CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous BRDT expression without altering the underlying DNA sequence.
BRDT CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the BRDT locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the BRDT transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous BRDT expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native BRDT locus and enabling the study of BRDT-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of BRDT pathway restoration in tumor cells with silenced or reduced BRDT expression.
