FOXP2 CRISPR Activation Plasmid (m): sc-431094-ACT

Foxp2 encodes the forkhead box transcription factor FOXP2, a sequence-specific regulator that coordinates gene programs controlling neuronal differentiation, migration, and synaptic plasticity. In the mouse nervous system, FOXP2 is prominently expressed in cortico-basal ganglia and cerebellar circuits, where it influences activity-dependent transcription and connectivity important for motor learning and vocalization-related behaviors. FOXP2 integrates with broader transcriptional and chromatin-regulatory networks to shape developmental timing and circuit maturation. Dysregulated FOXP2-dependent gene expression has been linked to altered neurodevelopmental phenotypes and provides a mechanistic entry point for studying transcriptional control in brain development and function.

FOXP2 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Foxp2 expression without altering the underlying DNA sequence.

FOXP2 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Foxp2 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 Foxp2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous FOXP2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Foxp2 locus and enabling the study of FOXP2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of FOXP2 pathway restoration in tumor cells with silenced or reduced Foxp2 expression.
