TMPRSS6 encodes matriptase-2, a liver-enriched type II transmembrane serine protease that functions as a key negative regulator of systemic iron homeostasis. Matriptase-2 suppresses hepcidin expression by proteolytically modulating the hemojuvelin (HJV)/BMP-SMAD signaling axis, thereby influencing ferroportin-mediated iron export and transferrin saturation. Through this pathway, TMPRSS6 integrates extracellular proteolysis with transcriptional control of iron metabolism genes. Genetic or functional dysregulation of TMPRSS6 is strongly associated with hepcidin-driven iron restriction phenotypes, making it a central target for mechanistic studies of iron regulation and erythropoiesis.
Matriptase-2 CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous TMPRSS6 expression without altering the underlying DNA sequence.
Matriptase-2 CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the TMPRSS6 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 TMPRSS6 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous Matriptase-2 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native TMPRSS6 locus and enabling the study of Matriptase-2-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of Matriptase-2 pathway restoration in tumor cells with silenced or reduced TMPRSS6 expression.
