MBNL1 Lentiviral Activation Particles (m) | sc-425296-LAC | 200 µl | $455.00 |
Mbnl1 encodes muscleblind-like splicing regulator 1 (MBNL1), an RNA-binding protein that recognizes YGCY motifs to control alternative splicing, mRNA localization, and stability during development and tissue maintenance. In mouse, MBNL1 coordinates splice isoform transitions that influence cytoskeletal organization, membrane excitability, and differentiation programs in muscle, heart, and neural tissues. Disruption of MBNL-family function is linked to widespread mis-splicing networks implicated in myotonic dystrophy pathobiology and other RNA processing disorders, making Mbnl1 a key node for studying splicing-dependent gene regulation. MBNL1-dependent RNA processing also intersects with stress-responsive transcriptome remodeling and cell state changes that can be measured by isoform-resolved RNA-seq and functional assays.
MBNL1 Lentiviral Activation Particles (m) address this need by packaging the complete synergistic activation mediator (SAM) transcriptional activation system into transduction-ready, high-titer lentiviral particles, enabling efficient Mbnl1 upregulation across a broader range of human cell types.
MBNL1 Lentiviral Activation Particles (m) 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 Mbnl1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous MBNL1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Mbnl1 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.
