hippocalcin Lentiviral Activation Particles (m): sc-420938-LAC
- Target species: mouse
- 200 µl of transduction-ready, high-titer CRISPR/dCas9 Lentiviral Activation Particles
- hippocalcin Lentiviral Activation Particles (m) is a synergistic activation mediator (SAM) transcription activation system designed to specifically and efficiently upregulate gene expression via lentiviral transduction of cells
- hippocalcin Lentiviral Activation Particles (m) contain the following SAM Activation elements: a deactivated Cas9 (dCas9) nuclease (D10A and N863A) fused to the transactivation domain VP64, an MS2-p65-HSF1 fusion protein and a target-specific 20 nt guide RNA. They also contain the blasticidin, hygromycin and puromycin resistance genes
- Upon transduction, the SAM complex binds to a site-specific region approximately 200-250 nt upstream of the transcriptional start site and provides robust recruitment of transcription factors for highly efficient gene activation
- gRNAs encoded by hippocalcin Lentiviral Activation Plasmid (m) and hippocalcin Lentiviral Activation Plasmid (m2) target distinct regulatory regions of the Hpca promoter. One or both designs may be available
- Following transfection, gene activation efficiency can be assayed by WB, IF or IHC using antibody: hippocalcin Antibody (G-8): sc-393125

Mouse Hpca encodes hippocalcin, a neuron-enriched EF-hand Ca2+-binding protein of the neuronal calcium sensor family that couples intracellular calcium transients to downstream signaling. Hippocalcin participates in synaptic activity–dependent processes including modulation of membrane excitability, calcium homeostasis, and vesicle-related trafficking, and it has been linked to pathways that shape long-term synaptic plasticity in hippocampal circuits. Through calcium-myristoyl switch–like behavior and interactions with neuronal signaling partners, it can influence Ca2+-regulated responses such as cAMP signaling, receptor dynamics, and activity-dependent gene expression programs. Dysregulation of hippocalcin-associated signaling has been studied in the context of neuronal stress responses and neurodegeneration-relevant phenotypes, supporting its use as a molecular entry point for mechanisms underlying cognitive and synaptic dysfunction.
hippocalcin 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 Hpca upregulation across a broader range of human cell types.
hippocalcin 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 Hpca transcriptional start site, where VP64, p65, and HSF1 act cooperatively to recruit endogenous transcriptional machinery and drive sustained upregulation of endogenous hippocalcin expression. The use of nuclease-inactive dCas9 avoids the introduction of double-strand DNA breaks and preserves the native Hpca 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.
