D2DR/Dopamine D2 Receptor Double Nickase Plasmid (m2) | sc-420053-NIC-2 | 20 µg | $410.00 |
Drd2 encodes the dopamine D2 receptor (D2DR), a Gi/o-coupled GPCR that inhibits adenylyl cyclase, reduces cAMP/PKA signaling, and modulates ion channel activity to shape neuronal excitability and synaptic transmission. D2DR is highly expressed in striatal medium spiny neurons where it integrates dopaminergic tone with glutamatergic inputs, influencing basal ganglia circuitry, motor control, motivation, and reward learning. Receptor signaling engages pathways including MAPK/ERK and β-arrestin–dependent cascades, linking neurotransmitter dynamics to gene expression programs and plasticity. Altered DRD2 function or expression is associated with neuropsychiatric and neurodegenerative research contexts, including studies of dopaminergic dysregulation, antipsychotic pharmacology, and circuit-level mechanisms of behavior.
D2DR/Dopamine D2 Receptor Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Drd2 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Drd2. 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 Drd2 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 Drd2-disrupted clones.
