YWHAQ encodes the human 14-3-3 theta adaptor protein, a member of the 14-3-3 family that binds phosphoserine/phosphothreonine motifs to modulate the localization, stability, and activity of diverse signaling proteins. Through these interactions, 14-3-3 theta helps coordinate cell-cycle control, stress responses, and apoptotic signaling, intersecting with kinase-driven networks such as MAPK/ERK, PI3K-AKT, and RAF-related pathways. Its scaffolding function influences protein trafficking and cytoskeletal dynamics, contributing to regulation of transcriptional programs and metabolic homeostasis. Dysregulated 14-3-3 interactions and altered YWHAQ expression have been associated with phenotypes relevant to cancer biology and neurobiology, supporting its use in mechanistic studies of signaling rewiring and cellular stress adaptation.
14-3-3 θ CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous YWHAQ expression without altering the underlying DNA sequence.
14-3-3 θ CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the YWHAQ 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 YWHAQ transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous 14-3-3 θ expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native YWHAQ locus and enabling the study of 14-3-3 θ-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of 14-3-3 θ pathway restoration in tumor cells with silenced or reduced YWHAQ expression.
