MCPIP Lentiviral Activation Particles (m) | sc-432978-LAC | 200 µl | $455.00 |
Mouse Zc3h12a encodes MCPIP (also known as Regnase-1), a CCCH-type zinc-finger RNA-binding endoribonuclease that limits inflammatory signaling by promoting decay of select cytokine and immune-response transcripts. MCPIP integrates with innate immune and stress-response pathways, modulating TLR/IL-1R–NF-κB signaling output and influencing mRNA stability programs that shape macrophage and T cell activation states. Through its roles in post-transcriptional gene regulation, MCPIP is widely studied in contexts of immune homeostasis, chronic inflammation, and autoimmunity-related mechanisms, as well as broader effects on cell differentiation and survival under inflammatory stress.
MCPIP 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 Zc3h12a upregulation across a broader range of human cell types.
MCPIP 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 Zc3h12a transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous MCPIP expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Zc3h12a 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.
