WDR77 (also known as MEP50) encodes a WD-repeat scaffolding protein that serves as an obligate cofactor for PRMT5, supporting symmetric dimethylation of arginine residues on histones and diverse RNA-binding proteins. Through this PRMT5–WDR77 methylosome complex, WDR77 influences chromatin organization, transcriptional control, and pre-mRNA splicing, with downstream effects on cell-cycle progression and lineage programs. WDR77 has also been linked to androgen receptor co-regulation and broader nuclear receptor signaling, connecting it to pathways that shape proliferation and differentiation states. Dysregulated PRMT5/WDR77 activity is frequently studied in cancer biology and developmental contexts where epigenetic and RNA-processing defects contribute to altered gene expression networks.
WDR77 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the WDR77 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within WDR77. 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 WDR77 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 WDR77-disrupted clones.
