BMPR2 encodes bone morphogenetic protein receptor type II (BMPR-II), a serine/threonine kinase receptor in the TGF-β/BMP superfamily that transduces extracellular BMP ligands to intracellular SMAD1/5/8 signaling. Upon ligand binding, BMPR-II partners with type I BMP receptors to drive phosphorylation cascades that regulate transcriptional programs controlling vascular homeostasis, smooth muscle cell behavior, and developmental patterning. BMPR2 signaling also interfaces with non-canonical pathways including MAPK and Rho GTPase networks, influencing cytoskeletal dynamics and cellular migration. Dysregulated BMPR2 activity or expression is strongly linked to pulmonary arterial hypertension biology and broader vascular remodeling phenotypes, making it a widely used target in mechanistic studies of BMP pathway regulation.
BMPR-II Lentiviral Activation Particles (h) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient BMPR2 upregulation across a broader range of human cell types.
BMPR-II Lentiviral Activation Particles (h) deliver all functional components of the synergistic activation mediator (SAM) system via lentiviral transduction. The system comprises three particle preparations co-transduced into target cells: one encoding catalytically inactive dCas9 (D10A and N863A mutations) fused to the VP64 transactivation domain with a blasticidin resistance gene; one encoding the MS2-p65-HSF1 fusion protein with a hygromycin resistance gene; and one encoding a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers with a puromycin resistance gene. Following lentiviral transduction and genomic integration of the expression cassettes, the SAM components are stably expressed and assemble at the target locus within the proximal promoter region upstream of the BMPR2 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous BMPR-II expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native BMPR2 genomic locus and regulatory architecture.
The lentiviral format offers several practical advantages: stable genomic integration supports heritable activation across cell divisions; high-titer particle preparations eliminate the need for in-house viral production; and compatibility with primary, non-dividing, and transfection-resistant cell types expands experimental accessibility. Successful transduction can be confirmed and enriched through triple antibiotic selection using puromycin, hygromycin, and blasticidin.
