Human HDAC4 encodes histone deacetylase 4, a class IIa HDAC that shuttles between nucleus and cytoplasm to modulate chromatin accessibility and transcriptional programs. HDAC4 functions in multiprotein co-repressor complexes and integrates calcium/calmodulin-dependent kinase and 14-3-3 signaling to regulate MEF2-driven gene expression, cell differentiation, and stress-responsive transcription. Through deacetylation-dependent control of histone and non-histone substrates, HDAC4 contributes to pathways governing muscle and neuronal development, synaptic plasticity, and metabolic homeostasis. Dysregulated HDAC4 activity and localization have been linked to aberrant epigenetic states observed across neurodevelopmental, neurodegenerative, and oncogenic contexts, making it a useful node for mechanistic studies of transcriptional repression.
Histone Deacetylase 4 (HDAC4) Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HDAC4 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HDAC4. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt HDAC4 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of HDAC4-disrupted clones.
