Mouse Grem1 encodes gremlin-1, a secreted DAN-family antagonist that binds BMP2, BMP4, and BMP7 to modulate BMP/TGF-β superfamily signaling and downstream SMAD-dependent transcription. By restraining BMP activity, gremlin-1 influences embryonic patterning, epithelial–mesenchymal interactions, and tissue homeostasis, and it can shape extracellular matrix remodeling and stromal–parenchymal crosstalk. Dysregulated Grem1 expression is associated with altered developmental programs and fibrosis-related processes, and it is frequently studied in contexts where BMP signaling governs lineage commitment and microenvironmental regulation. In mouse models, Grem1 provides a tractable node for dissecting BMP pathway dynamics across organogenesis and disease-relevant remodeling states.
gremlin-1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Grem1 expression without altering the underlying DNA sequence.
gremlin-1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Grem1 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 Grem1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous gremlin-1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Grem1 locus and enabling the study of gremlin-1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of gremlin-1 pathway restoration in tumor cells with silenced or reduced Grem1 expression.
