Gβ 1 Lentiviral Activation Particles (m2) | sc-420606-LAC-2 | 200 µl | $455.00 |
Mouse Gnb1 encodes the heterotrimeric G protein subunit Gβ1, a core component of GPCR signaling that forms obligate dimers with Gγ subunits to regulate Gα activity and propagate signals to effectors such as adenylyl cyclases, phospholipase Cβ, and ion channels. Through these interactions, Gβ1 helps coordinate second-messenger dynamics, membrane excitability, and kinase cascades including MAPK/ERK, shaping cellular responses to neurotransmitters, hormones, and sensory cues. Altered Gβ1-dependent signaling is relevant to studies of neurodevelopmental and neurophysiological dysfunction, where perturbations in GPCR pathway balance can impact synaptic transmission and network activity. Gnb1 gene editing or perturbation in mouse models supports mechanistic dissection of GPCR-effector coupling, signal bias, and pathway cross-talk using assays such as cAMP/PLC readouts, electrophysiology, and phosphoproteomic profiling.
Gβ 1 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 Gnb1 upregulation across a broader range of human cell types.
Gβ 1 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 Gnb1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Gβ 1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Gnb1 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.
