Vaccinia-related kinase 1 (VRK1) is a serine/threonine kinase that localizes primarily to the nucleus and regulates chromatin dynamics, cell-cycle progression, and DNA damage responses. VRK1 phosphorylates substrates such as histone H3 and p53, linking it to mitotic entry, transcriptional control, and checkpoint signaling pathways that safeguard genome integrity. Through modulation of nuclear envelope and chromatin-associated processes, VRK1 helps coordinate proliferation with replication stress and repair. Altered VRK1 activity or expression has been associated with neurodevelopmental and neuromuscular phenotypes and is frequently studied in the context of aberrant cell growth and genome stability.
VRK1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the VRK1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within VRK1. 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 VRK1 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 VRK1-disrupted clones.
