DIAPH1 encodes the formin protein Dia1, an actin nucleation and elongation factor that coordinates cytoskeletal remodeling downstream of RhoA signaling. Dia1 supports linear F-actin assembly, stress fiber formation, and microtubule stabilization, thereby influencing cell polarity, adhesion, cytokinesis, and directed migration. Through its roles in cytoskeletal dynamics and mechanotransduction, DIAPH1 helps regulate processes such as cell division and tissue architecture. Altered DIAPH1 activity has been associated with human disease phenotypes including sensorineural hearing loss and thrombocytopenia, and it is frequently studied in contexts where actin-dependent motility and proliferation are dysregulated.
Dia 1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DIAPH1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DIAPH1. 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 DIAPH1 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 DIAPH1-disrupted clones.
