GA-binding protein subunit beta 1 (GABPB1) encodes the β1/β2 partner that heterodimerizes with GABPA to form the ETS-family transcription factor GABP, which binds GA-rich promoter elements and coordinates gene expression programs controlling cell-cycle progression, mitochondrial biogenesis, and proteostasis. GABP complexes regulate nuclear-encoded mitochondrial genes and oxidative phosphorylation capacity, and they contribute to transcriptional control of telomere maintenance through TERT promoter regulation. Through these functions, GABPB1 intersects with pathways governing cellular metabolism, stress adaptation, and lineage-specific transcriptional networks. Dysregulation of GABP signaling and altered GABPB1-dependent transcriptional output have been implicated in contexts of tumor biology and disorders with mitochondrial or transcriptional control defects, supporting mechanistic studies of gene regulation and cellular fitness.
GABP-β1/2 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GABPB1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GABPB1. 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 GABPB1 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 GABPB1-disrupted clones.
