LHR CRISPR Activation Plasmid (h) | sc-400750-ACT | 20 µg | $397.00 |
LHCGR encodes the human luteinizing hormone/choriogonadotropin receptor (LHR), a rhodopsin-like G protein-coupled receptor that binds luteinizing hormone and chorionic gonadotropin to regulate gonadal steroidogenesis and reproductive tissue function. Upon ligand engagement, LHR primarily activates Gαs–adenylyl cyclase–cAMP/PKA signaling and can intersect with MAPK/ERK and PI3K/AKT pathways to modulate transcriptional programs, cell differentiation, and endocrine feedback. Dysregulated LHCGR expression or signaling has been associated with reproductive endocrine phenotypes, including impaired gonadal function and altered steroid hormone biosynthesis. In biomedical research, LHCGR is used to interrogate GPCR signaling dynamics, gonadotropin-driven gene regulation, and pathway crosstalk relevant to reproductive biology and hormone-responsive systems.
LHR CRISPR Activation Plasmid (h) provides a targeted, non-destructive approach to upregulating endogenous LHCGR expression without altering the underlying DNA sequence.
LHR CRISPR Activation Plasmid (h) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the LHCGR 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 LHCGR transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous LHR expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native LHCGR locus and enabling the study of LHR-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of LHR pathway restoration in tumor cells with silenced or reduced LHCGR expression.
