TRIM71 encodes the RNA-binding E3 ubiquitin ligase LIN-41, a conserved regulator of post-transcriptional gene control that coordinates mRNA stability and translation through its TRIM and NHL domains. LIN-41 participates in developmental timing and stem cell programs by modulating differentiation, cell-cycle progression, and proteostasis, and it interfaces with microRNA-mediated regulation, including the let-7 pathway. In human cells, TRIM71 activity is linked to maintenance of pluripotency and neural lineage decisions, with dysregulation implicated in aberrant growth and developmental phenotypes. These properties make TRIM71 a useful target for dissecting RNA regulons, ubiquitin-dependent signaling, and lineage commitment mechanisms.
LIN-41 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TRIM71 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TRIM71. 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 TRIM71 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 TRIM71-disrupted clones.
