SUMO2 encodes SUMO-2, a ubiquitin-like modifier that is covalently conjugated to substrate proteins to regulate localization, stability, and protein–protein interactions through SUMOylation. SUMO-2/3 modification is rapidly induced by cellular stress and participates in DNA damage responses, chromatin organization, transcriptional regulation, and cell-cycle control via coordinated activity of E1 (SAE1/SAE2), E2 (UBE2I/UBC9), and E3 ligases such as PIAS family members. By tuning pathways including NF-κB signaling, p53-mediated checkpoints, and replication stress tolerance, SUMO-2 helps maintain proteostasis and genome integrity. Dysregulated SUMOylation has been associated with oncogenic transformation, neurodegeneration, and inflammatory signaling, making SUMO2 a broadly relevant node for mechanistic studies.
SUMO-2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the SUMO2 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within SUMO2. 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 SUMO2 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 SUMO2-disrupted clones.
