BPTF Lentiviral Activation Particles (h) | sc-404092-LAC | 200 µl | $455.00 |
BPTF (bromodomain PHD finger transcription factor) is a core component of the NURF chromatin-remodeling complex that recognizes histone marks through its PHD finger and bromodomain to regulate nucleosome positioning and transcriptional output. By modulating chromatin accessibility, BPTF influences RNA polymerase II–dependent gene expression programs involved in cell cycle control, lineage specification, and DNA damage responses. It participates in epigenetic regulation across developmental and proliferative pathways, linking histone modification landscapes to transcription factor activity. Dysregulated BPTF expression or function has been associated with altered chromatin states observed in cancer biology and neurodevelopmental processes, making it a useful node for mechanistic studies of transcriptional regulation.
BPTF Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient BPTF upregulation across a broader range of human cell types.
BPTF Lentiviral Activation Particles (h) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the BPTF transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous BPTF expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native BPTF genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
