PHF5A Lentiviral Activation Particles (h) | sc-407986-LAC | 200 µl | $455.00 |
PHF5A encodes PHD finger protein 5A, an essential component of the SF3b subcomplex within the U2 small nuclear ribonucleoprotein that supports pre-mRNA splicing and spliceosome assembly. By helping define 3′ splice site recognition, PHF5A influences alternative splicing decisions that couple to transcriptional control, cell-cycle progression, and DNA damage responses. Perturbation of PHF5A-dependent splicing can remodel transcript isoform landscapes and alter expression of genes involved in proliferation and genome maintenance. Dysregulated spliceosome function and splice site selection are frequently implicated in cancer biology and other disorders with aberrant RNA processing, making PHF5A a relevant node for mechanistic studies.
PHF5A 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 PHF5A upregulation across a broader range of human cell types.
PHF5A 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 PHF5A transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous PHF5A expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native PHF5A 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.
