GNAO1 encodes the human heterotrimeric G protein α subunit Gαo, a predominant inhibitory G protein in the nervous system that couples many GPCRs to downstream effectors. Upon receptor activation, Gαo regulates adenylyl cyclase and coordinates signaling through βγ subunits to modulate ion channels, vesicle trafficking, and neurotransmitter release, shaping synaptic transmission and neuronal excitability. This signaling node integrates with cAMP-dependent pathways and broader GPCR-regulated networks that control differentiation and circuit activity. Dysregulation of GNAO1-dependent signaling has been linked to neurodevelopmental and movement disorder phenotypes, making it relevant for mechanistic studies in neuronal models and signal transduction assays.
Gα o Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GNAO1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GNAO1. 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 GNAO1 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 GNAO1-disrupted clones.
