STAMP2 CRISPR Activation Plasmid (m) | sc-431182-ACT | 20 µg | $397.00 |
Mouse Steap4 encodes STAMP2, a six-transmembrane metalloreductase that supports cellular redox control by facilitating ferric and cupric reduction and coordinating metal-dependent signaling. STAMP2 is induced by inflammatory and metabolic cues and has been linked to pathways regulating adipocyte function, insulin responsiveness, and cytokine-driven stress responses. In immune and metabolic tissues, STAMP2 influences reactive oxygen species balance and endoplasmic reticulum homeostasis, processes that shape macrophage activation and adipose tissue remodeling. Dysregulation of Steap4 expression has been associated with inflammatory states and metabolic dysfunction, making it a useful node for studying immunometabolic crosstalk in mouse models.
STAMP2 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Steap4 expression without altering the underlying DNA sequence.
STAMP2 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Steap4 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 Steap4 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous STAMP2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Steap4 locus and enabling the study of STAMP2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of STAMP2 pathway restoration in tumor cells with silenced or reduced Steap4 expression.
