EYA1 CRISPR Activation Plasmid (h) | sc-404056-ACT | 20 µg | $397.00 |
Human EYA1 (eyes absent homolog 1) encodes a transcriptional coactivator and haloacid dehalogenase–family phosphatase that integrates developmental signaling with gene regulatory programs. EYA1 functions in concert with SIX and DACH proteins to control organogenesis and cell fate decisions, and it also participates in DNA damage responses through modulation of phosphorylation-dependent signaling. Dysregulated EYA1 activity or expression is linked to congenital developmental disorders affecting ear and kidney morphogenesis and has been investigated in contexts where altered differentiation and proliferation programs contribute to disease phenotypes. As a nuclear-cytoplasmic regulator, EYA1 provides a tractable node for studying transcriptional control, phosphatase biology, and developmental pathway crosstalk.
EYA1 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous EYA1 expression without altering the underlying DNA sequence.
EYA1 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the EYA1 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 EYA1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous EYA1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native EYA1 locus and enabling the study of EYA1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of EYA1 pathway restoration in tumor cells with silenced or reduced EYA1 expression.
