ERK 1 Lentiviral Activation Particles (h) | sc-400010-LAC | 200 µl | $455.00 |
MAPK3 encodes extracellular signal-regulated kinase 1 (ERK1), a serine/threonine kinase that integrates upstream cues from receptor tyrosine kinases, RAS–RAF signaling, and MEK1/2 to control phosphorylation-dependent programs in proliferation, differentiation, survival, and stress responses. ERK1 functions within the canonical MAPK/ERK cascade and modulates nuclear and cytoplasmic substrates, including transcription factors and cell-cycle regulators, to shape context-specific gene expression. Dysregulated ERK pathway activity is frequently associated with aberrant growth signaling and altered cell fate decisions in diverse disease settings, making MAPK3 a central node for mechanistic studies of signaling dynamics and pathway crosstalk.
ERK 1 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 MAPK3 upregulation across a broader range of human cell types.
ERK 1 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 MAPK3 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous ERK 1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native MAPK3 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.
