CRHBP encodes corticotropin-releasing factor–binding protein (CRF-BP), a secreted glycoprotein that binds CRH and related urocortins to regulate ligand bioavailability and receptor engagement within the hypothalamic–pituitary–adrenal (HPA) axis. By buffering free CRH family peptides, CRF-BP modulates downstream CRHR1/CRHR2 signaling pathways that converge on cAMP/PKA and transcriptional programs controlling stress responsiveness, neuroendocrine secretion, and inflammatory tone. CRHBP expression is prominent in brain and peripheral tissues, where it can influence neuroimmune communication and endocrine homeostasis. Dysregulation of CRH–urocortin signaling and CRHBP expression patterns has been associated with stress-related neuropsychiatric phenotypes, altered metabolic regulation, and inflammatory processes, making it relevant for mechanistic studies of stress circuitry and peripheral CRF biology.
CRF-BP Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CRHBP locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within CRHBP. 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 CRHBP 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 CRHBP-disrupted clones.
