Mouse Hap1 encodes huntingtin-associated protein 1 (HAP1), a neuron-enriched cytoplasmic scaffold implicated in intracellular trafficking, vesicle transport, and cytoskeletal organization. HAP1 interacts with motor and adaptor complexes that support endosomal dynamics and receptor/transporter localization, linking it to synaptic maintenance and neuronal homeostasis. Through these roles, HAP1 is studied in pathways relevant to neurodegeneration and neurodevelopment, including processes tied to protein transport and stress-responsive cellular organization. Altered HAP1-associated trafficking and proteostasis have been investigated in the context of Huntington’s disease biology and broader neuronal vulnerability mechanisms.
HAP1 CRISPR Activation Plasmid (m) provides a targeted, non-destructive approach to upregulating endogenous Hap1 expression without altering the underlying DNA sequence.
HAP1 CRISPR Activation Plasmid (m) is a three-plasmid synergistic activation mediator (SAM) system engineered for highly efficient, site-specific transcriptional upregulation of the Hap1 locus in human cell lines. The system is built around a catalytically inactive Cas9 (dCas9) carrying two inactivating mutations (D10A and N863A) that eliminate nuclease activity while preserving DNA binding. This dCas9 is fused to VP64, a potent transcriptional activator, and is co-expressed with a blasticidin resistance gene for selection. The second plasmid encodes the MS2-p65-HSF1 fusion protein, a secondary activator complex that works in concert with dCas9-VP64, alongside a hygromycin resistance gene. The third plasmid encodes a target-specific 20 nt sgRNA fused to two MS2 RNA aptamers that recruit the MS2-p65-HSF1 complex to the activation site, accompanied by a puromycin resistance gene. The three plasmids are delivered at a 1:1:1 mass ratio for balanced expression of all system components.
Once assembled at the target locus, the SAM complex binds within approximately 200 bp upstream of the Hap1 transcriptional start site, where VP64, p65, and HSF1 act in concert to recruit transcriptional machinery and drive upregulation of endogenous HAP1 expression. Unlike nuclease-active Cas9, dCas9 does not introduce double-strand breaks or modify the genomic sequence, preserving the native Hap1 locus and enabling the study of HAP1-dependent transcriptional responses at the endogenous locus, making it a valuable tool for functional studies, target gene identification, and the modeling of HAP1 pathway restoration in tumor cells with silenced or reduced Hap1 expression.
