CACNB2 encodes the β2 auxiliary subunit of L-type voltage-gated calcium channels, regulating channel trafficking, membrane expression, and gating kinetics that shape Ca2+ influx during depolarization. By tuning CaV1 channel activity, CACNB2 influences excitation–contraction coupling, synaptic transmission, and activity-dependent gene regulation through calcium-sensitive pathways such as CaMK and calcineurin/NFAT signaling. Altered CACNB2 function has been associated with electrical and signaling abnormalities in excitable tissues and is frequently studied in the context of arrhythmia susceptibility, neuropsychiatric phenotypes, and other calcium channel–related disorders. As an accessory subunit, β2 also impacts pharmacologic sensitivity and biophysical properties of L-type Ca2+ currents, making it relevant for mechanistic studies of channelopathies.
L-type Ca++ CP β2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CACNB2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CACNB2. 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 CACNB2 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 CACNB2-disrupted clones.
