CBL encodes Cbl, an E3 ubiquitin ligase and adaptor protein that coordinates downregulation of activated receptor and non-receptor tyrosine kinases. Through its TKB domain and RING finger–dependent ubiquitination activity, Cbl promotes ubiquitin-mediated trafficking and degradation of signaling complexes, shaping outputs from pathways such as EGFR/RTK, MAPK/ERK, PI3K–AKT, and immune receptor signaling. Cbl also contributes to endocytosis, protein quality control, and feedback regulation of signal transduction intensity and duration. Dysregulation or mutation of CBL is linked to aberrant tyrosine kinase signaling and hematologic disease biology, making it a useful node for probing oncogenic signaling networks and immune cell regulatory circuits.
Cbl Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CBL locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CBL. 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 CBL 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 CBL-disrupted clones.
