AMPKβ1 Lentiviral Activation Particles (h) | sc-402952-LAC | 200 µl | $455.00 |
PRKAB1 encodes the β1 regulatory subunit of AMP-activated protein kinase (AMPK), a central energy sensor that integrates cellular AMP/ATP status to coordinate metabolic homeostasis. AMPKβ1 contributes to heterotrimer assembly, subcellular localization, and glycogen binding, influencing downstream control of glucose uptake, fatty acid oxidation, autophagy, and inhibition of anabolic signaling through pathways such as mTORC1. Through these functions, AMPKβ1 helps couple nutrient availability and stress responses to transcriptional and post-translational programs that preserve energy balance. Dysregulation of AMPK signaling and PRKAB1-associated complexes is relevant to research on metabolic remodeling in cancer, insulin resistance, and other disorders linked to altered mitochondrial function and nutrient sensing.
AMPKβ1 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 PRKAB1 upregulation across a broader range of human cell types.
AMPKβ1 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 PRKAB1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous AMPKβ1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native PRKAB1 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.
