GDI1 encodes Rab GDP dissociation inhibitor alpha, a cytosolic regulator that binds prenylated Rab GTPases and controls their extraction from membranes, solubilization, and delivery to target compartments during vesicular trafficking. By modulating Rab cycling between membrane- and cytosol-associated pools, Rab GDI α helps coordinate endocytic and exocytic transport, organelle identity, and membrane dynamics across pathways such as endosome-to-Golgi transport and synaptic vesicle recycling. Proper GDI1 function supports neuronal trafficking demands, and altered regulation of Rab-dependent transport has been linked to neurodevelopmental and cognitive phenotypes. In human systems, GDI1 is frequently studied as a node connecting Rab GTPase signaling to proteostasis, membrane receptor turnover, and compartment-specific transport fidelity.
Rab GDI α Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GDI1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GDI1. 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 GDI1 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 GDI1-disrupted clones.
