HAS2 CRISPR Activation Plasmid (h) | sc-401032-ACT | 20 µg | $397.00 |
Human HAS2 encodes hyaluronan synthase 2, a plasma membrane enzyme that polymerizes hyaluronan, a major extracellular matrix glycosaminoglycan that regulates tissue hydration, viscoelasticity, and pericellular matrix assembly. HAS2-driven hyaluronan production shapes cell adhesion and migration programs through CD44 and RHAMM signaling and intersects with EMT, inflammatory cues, and mechanotransduction pathways that remodel the tumor microenvironment and fibrotic stroma. Transcriptional control of HAS2 integrates inputs from TGF-β, NF-κB, and growth factor signaling, linking extracellular matrix dynamics to proliferative and stress-response programs. Dysregulated HAS2 activity and hyaluronan accumulation are frequently studied in cancer invasion and metastasis, fibrosis, vascular remodeling, and inflammatory pathologies.
HAS2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous HAS2 expression without altering the underlying DNA sequence.
HAS2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the HAS2 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 HAS2 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous HAS2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native HAS2 locus and enabling the study of HAS2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of HAS2 pathway restoration in tumor cells with silenced or reduced HAS2 expression.
