GNB2 encodes the human Gβ2 subunit of heterotrimeric G proteins, a core component of GPCR signal transduction that couples activated receptors to downstream effectors. By forming obligate dimers with Gγ subunits and assembling with Gα, Gβ2 influences second-messenger pathways including cAMP/PKA, PLCβ–IP3/DAG–Ca²⁺ signaling, and ion channel regulation, shaping cellular responses such as chemotaxis, secretion, and neuronal excitability. Perturbation of G protein subunit balance can rewire signaling networks that govern proliferation, differentiation, and immune cell trafficking. Accordingly, altered GNB2-associated GPCR circuitry is frequently investigated in the context of dysregulated signaling states and pathway dependencies in human disease biology.
Gβ 2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GNB2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GNB2. 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 GNB2 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 GNB2-disrupted clones.
