GRIN1 CRISPR Activation Plasmid (h) | sc-405452-ACT | 20 µg | $397.00 |
GPRIN1 (G protein-regulated inducer of neurite outgrowth 1) encodes a neuron-enriched protein implicated in neurite extension, growth cone dynamics, and synaptic maturation through modulation of G protein–coupled signaling and cytoskeletal remodeling. GRIN1-associated processes intersect with neuronal differentiation programs and activity-dependent pathways that shape connectivity and plasticity. Dysregulated expression or network perturbation involving GPRIN1 has been explored in the context of neurodevelopmental and neuropsychiatric disease biology, where altered neuritogenesis and synaptic function are recurring themes. As a human neuronal signaling effector, GPRIN1 provides a tractable target for mechanistic studies of connectivity-related phenotypes in relevant cellular models.
GRIN1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous GPRIN1 expression without altering the underlying DNA sequence.
GRIN1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the GPRIN1 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the GPRIN1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous GRIN1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native GPRIN1 locus and enabling the study of GRIN1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of GRIN1 pathway restoration in tumor cells with silenced or reduced GPRIN1 expression.
