WDR5 Lentiviral Activation Particles (m2) | sc-431247-LAC-2 | 200 µl | $455.00 |
Mouse Wdr5 encodes WDR5, a conserved WD40 repeat scaffold protein that is a core component of SET/MLL family histone H3K4 methyltransferase complexes and coordinates chromatin-associated assembly factors to regulate transcriptional programs. WDR5 supports epigenetic control of gene expression through promoter and enhancer regulation, influencing cell cycle progression, lineage specification, and developmental patterning, and it interfaces with broader chromatin remodeling and RNA processing networks. Dysregulated WDR5-dependent chromatin states are linked to altered differentiation and proliferative phenotypes observed in cancer and other epigenetically driven disorders, making Wdr5 a valuable target for mechanistic studies of transcriptional regulation. Gene editing of Wdr5 in mouse models enables functional dissection of H3K4 methylation pathways, mapping of protein–protein interactions within COMPASS/MLL complexes, and investigation of context-specific effects on stem cell biology and tissue homeostasis.
WDR5 Lentiviral Activation Particles (m2) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Wdr5 upregulation across a broader range of human cell types.
WDR5 Lentiviral Activation Particles (m2) 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 Wdr5 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous WDR5 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Wdr5 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.
