Mfn1/Mitofusin 1 Lentiviral Activation Particles (m) | sc-426545-LAC | 200 µl | $455.00 |
Mouse Mfn1 (Mitofusin 1) encodes a dynamin-like GTPase localized to the outer mitochondrial membrane that drives mitochondrial fusion and maintains organelle morphology. MFN1 coordinates with MFN2 and OPA1 to regulate mitochondrial network remodeling, cristae organization, and bioenergetic efficiency, influencing ATP production and reactive oxygen species homeostasis. Through control of mitochondrial dynamics, MFN1 impacts processes including mitophagy, apoptosis sensitivity, and calcium handling at mitochondria–ER contact sites. Dysregulated fusion–fission balance involving MFN1 has been linked to mechanisms relevant to neurodegeneration, cardiometabolic stress, and altered cell survival programs in multiple disease models.
Mfn1/Mitofusin 1 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 Mfn1 upregulation across a broader range of human cell types.
Mfn1/Mitofusin 1 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 Mfn1 transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous Mfn1/Mitofusin 1 expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Mfn1 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.
