CARP Lentiviral Activation Particles (h) | sc-401842-LAC | 200 µl | $455.00 |
Human ANKRD1 encodes cardiac ankyrin repeat protein (CARP), a stress- and stretch-responsive transcriptional cofactor that links sarcomeric integrity to nuclear gene regulation. CARP participates in mechanotransduction programs in striated muscle, modulating expression of contractile and extracellular matrix genes and coordinating remodeling responses to altered load. It interacts with structural and signaling components in the Z-disc/I-band region and interfaces with pathways governing myofibrillogenesis, hypertrophic signaling, and cellular stress responses. Dysregulated ANKRD1 expression and/or function has been associated with cardiomyopathy-related remodeling phenotypes, making it a relevant target for studies of cardiac gene networks, muscle differentiation, and disease-associated transcriptional states.
CARP 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 ANKRD1 upregulation across a broader range of human cell types.
CARP 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 ANKRD1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous CARP expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native ANKRD1 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.
