UNC45A Lentiviral Activation Particles (m) | sc-430401-LAC | 200 µl | $455.00 |
Unc45a encodes UNC45A, a UCS-domain myosin chaperone that cooperates with HSP90 to promote proper folding, stabilization, and functional cycling of non-muscle myosins. Through regulation of actomyosin dynamics, UNC45A supports cytoskeletal organization, vesicle trafficking, and cell migration, linking it to processes such as cytokinesis and epithelial polarity. Altered UNC45A activity can perturb proteostasis and contractility-dependent signaling pathways, with downstream effects on tissue homeostasis and stress responses. These functions make mouse UNC45A a relevant target for mechanistic studies of cytoskeleton-associated phenotypes and gene networks that influence proliferative and migratory behavior.
UNC45A 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 Unc45a upregulation across a broader range of human cell types.
UNC45A 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 Unc45a transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous UNC45A expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Unc45a 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.
