GDF-9B CRISPR Activation Plasmid (h) | sc-403596-ACT | 20 µg | $397.00 |
BMP15 encodes growth differentiation factor 9B (GDF-9B), an oocyte-derived member of the TGF-β superfamily that regulates granulosa cell proliferation and differentiation during folliculogenesis. GDF-9B signals through BMP/SMAD pathways, influencing transcriptional programs that coordinate ovarian follicle growth, oocyte–somatic cell communication, and extracellular matrix remodeling. Altered BMP15 activity is associated with reproductive phenotypes including impaired ovarian function and infertility-related traits, making it relevant to studies of gonadal development and endocrine regulation. In addition, BMP15/GDF-9B cross-talk with related ligands and receptors provides a tractable model for dissecting context-dependent TGF-β family signaling.
GDF-9B CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous BMP15 expression without altering the underlying DNA sequence.
GDF-9B CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the BMP15 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 BMP15 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous GDF-9B expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native BMP15 locus and enabling the study of GDF-9B-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of GDF-9B pathway restoration in tumor cells with silenced or reduced BMP15 expression.
