TRB-1 Double Nickase Plasmid (h) | sc-405781-NIC | 20 µg | $410.00 |
Human TRIB1 encodes tribbles pseudokinase 1 (TRB-1), a catalytically inactive kinase-like scaffold that modulates signaling outputs by recruiting E3 ubiquitin ligases and shaping protein stability. TRB-1 participates in regulation of MAPK/ERK signaling, transcriptional programs controlling myeloid differentiation, and cellular stress responses, in part through interactions that influence ubiquitination and turnover of key pathway components. Altered TRIB1 expression has been associated with dysregulated lipid and glucose metabolism, inflammatory signaling, and hematopoietic lineage commitment, linking it to phenotypes relevant to metabolic and cardiovascular traits and myeloid malignancy biology. These functions make TRB-1 a useful node for interrogating pathway crosstalk between growth-factor signaling, proteostasis, and transcriptional control in human cells.
TRB-1 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the TRIB1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within TRIB1. 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 TRIB1 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 TRIB1-disrupted clones.
