CLK2 Lentiviral Activation Particles (h) | sc-403326-LAC | 200 µl | $455.00 |
Human CDC-like kinase 2 (CLK2) is a dual-specificity serine/threonine kinase that phosphorylates SR-rich splicing factors, coordinating spliceosome dynamics and alternative pre-mRNA splicing. CLK2 activity links transcription to RNA processing and contributes to regulation of cell-cycle progression and stress-responsive signaling, including pathways that modulate RNA metabolism and kinase networks. Dysregulated CLK2 expression or signaling has been associated with aberrant splicing programs observed in cancer and other disorders characterized by altered gene expression control. Because splicing decisions shape proteome diversity, CLK2 is frequently studied to understand how phosphorylation-dependent splicing regulation influences cellular phenotype.
CLK2 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 CLK2 upregulation across a broader range of human cell types.
CLK2 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 CLK2 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous CLK2 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native CLK2 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.
