Human RPL39 encodes ribosomal protein L39, a small basic component of the 60S large ribosomal subunit that contributes to ribosome assembly and stable translation of mRNAs. As part of the core translational machinery, RPL39 influences protein synthesis capacity, co-translational quality control, and broader cellular programs linked to growth, stress responses, and proteostasis. Perturbation of ribosomal proteins can elicit nucleolar stress and downstream signaling changes, including p53-dependent checkpoints, and may alter translational selectivity for specific transcripts. Dysregulation of ribosome biogenesis and function is widely implicated in ribosomopathies and cancer-related translational reprogramming, making RPL39 a relevant target for studying how altered ribosome composition impacts cell state and disease-associated phenotypes.
Ribosomal Protein L39 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the RPL39 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within RPL39. 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 RPL39 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 RPL39-disrupted clones.
