IP3R-I CRISPR/Cas9 KO Plasmid (h) | sc-400986 | 20 µg | $397.00 |
ITPR1 encodes inositol 1,4,5-trisphosphate receptor type 1 (IP3R-I), an endoplasmic reticulum Ca²⁺ release channel that converts IP₃ signals downstream of PLC-coupled receptors into cytosolic and mitochondrial calcium transients. IP3R-I-mediated Ca²⁺ flux regulates excitation–transcription coupling, synaptic plasticity, secretion, and apoptosis, and integrates with pathways such as GPCR/RTK–PLCβ/γ–IP₃ signaling, calmodulin/CaMK, calcineurin–NFAT, and ER–mitochondria contact site communication. ITPR1 activity shapes calcium homeostasis and stress responses, influencing cellular phenotypes including neuronal firing, autophagy, and unfolded protein response signaling. Genetic variation or dysregulation of ITPR1 has been linked to neurological dysfunction, including spinocerebellar ataxia phenotypes, making it a useful target for mechanistic studies of calcium signaling in human cells.
IP3R-I CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the ITPR1 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the ITPR1 together with the Streptococcus pyogenes Cas9 nuclease. The plasmids also encode GFP, allowing fluorescent identification and enrichment of successfully transfected cells by fluorescence microscopy or flow cytometry.
The multi-guide design increases the likelihood of generating insertions or deletions (indels) that disrupt the ITPR1 open reading frame following Cas9-mediated double-strand break formation. DNA breaks introduced by the CRISPR/Cas9 system are repaired through endogenous non-homologous end joining (NHEJ) pathways, frequently resulting in frameshift mutations that abolish IP3R-I protein expression.
This CRISPR knockout system enables efficient generation of ITPR1-deficient cell models for investigation of IP3R-I signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.
