SLC29A2 encodes equilibrative nucleoside transporter 2 (ENT2), a broadly expressed plasma membrane transporter that mediates bidirectional, concentration-dependent flux of purine and pyrimidine nucleosides. ENT2 supports nucleoside salvage pathways that sustain nucleotide pools for DNA/RNA synthesis and contributes to cellular responses to metabolic stress by regulating extracellular and intracellular nucleoside availability. By shaping nucleoside homeostasis, ENT2 intersects with processes such as cell-cycle progression, replication stress responses, and nucleoside-dependent signaling in many tissues. Altered SLC29A2/ENT2 activity and expression have been investigated in contexts including tumor biology, immune cell function, and transporter-related variation in cellular sensitivity to nucleoside analogs, supporting its relevance for mechanistic studies.
ENT2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SLC29A2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SLC29A2. 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 SLC29A2 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 SLC29A2-disrupted clones.
