GNA11 encodes the human heterotrimeric G protein α subunit Gα11, a key transducer for Gq/11-coupled GPCR signaling at the plasma membrane. Upon receptor activation, Gα11 stimulates phospholipase C-β, elevating IP3 and DAG to drive intracellular Ca2+ mobilization and protein kinase C activation, with downstream effects on MAPK and other second-messenger pathways. This signaling axis regulates proliferation, secretion, cytoskeletal dynamics, and receptor desensitization across diverse cell types. Dysregulated GNA11 activity has been linked to oncogenic signaling and altered endocrine and melanocytic biology, making it a relevant node for pathway dissection in disease-relevant models.
Gα 11 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GNA11 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GNA11. 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 GNA11 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 GNA11-disrupted clones.
