Mouse Kcnk2 encodes TREK-1, a mechanosensitive two-pore domain potassium (K2P) channel that provides background K+ conductance to stabilize resting membrane potential and tune neuronal and glial excitability. TREK-1 integrates signals from membrane stretch, temperature, intracellular pH, and lipid mediators to couple biophysical cues to changes in membrane polarization, shaping action potential firing and synaptic transmission. Through its role in maintaining ionic homeostasis, TREK-1 influences processes such as neuroprotection, pain signal processing, and stress-responsive circuit activity. Altered Kcnk2/TREK-1 function has been studied in the context of neurological and neuropsychiatric phenotypes, making it relevant for mechanistic pathway interrogation in mouse model systems.
TREK-1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Kcnk2 expression without altering the underlying DNA sequence.
TREK-1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Kcnk2 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 Kcnk2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous TREK-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Kcnk2 locus and enabling the study of TREK-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of TREK-1 pathway restoration in tumor cells with silenced or reduced Kcnk2 expression.
