ZNF138 encodes a KRAB-domain zinc finger protein that is predicted to function as a sequence-specific transcriptional regulator, coupling DNA-binding by C2H2 zinc fingers to epigenetic silencing through KRAB-associated co-repressor complexes. By recruiting chromatin-modifying factors, ZNF138 is expected to influence heterochromatin organization, transcriptional repression, and maintenance of cell-type–specific gene expression programs. Dysregulation of KRAB-ZNF networks has been linked to altered genome stability, aberrant differentiation, and oncogenic transcriptional states, supporting investigation of ZNF138 in disease-relevant gene regulatory pathways. Human ZNF138 is therefore a useful target for studying chromatin-dependent control of transcription and its impact on cellular phenotype.
ZNF138 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the ZNF138 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within ZNF138. 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 ZNF138 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 ZNF138-disrupted clones.
