Synip CRISPR/Cas9 KO Plasmid (h): sc-408351
- Target species: human
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- Synip CRISPR/Cas9 Knockout (KO) Plasmid (h) is a pool of plasmids, each encoding Cas9 nuclease and a target-specific 20 nt guide RNA (gRNA) designed for maximum knockout efficiency using sequences derived from the GeCKO v2 library
- gRNA sequences direct Cas9 to induce site-specific double-strand breaks (DSBs) in the Synip genomic locus, resulting in gene knockout through non-homologous end joining (NHEJ)
- The puromycin resistance and RFP genes are flanked by LoxP sites, enabling removal of selection markers via Cre recombinase (Cre Vector: sc-418923) after establishing stable knockout cell lines

Overview
Human STXBP4 encodes Synip (syntaxin-binding protein 4), a cytosolic regulator of SNARE-mediated membrane fusion that modulates vesicle trafficking and stimulus-dependent exocytosis. Synip interacts with syntaxin family members to influence docking and fusion dynamics at the plasma membrane, thereby impacting membrane protein delivery and turnover. Through its role in trafficking programs linked to insulin-responsive transport and broader secretory processes, STXBP4 can affect cellular metabolism, signaling amplitude, and membrane compartment organization. Altered Synip-dependent trafficking has been investigated in contexts including metabolic dysregulation and cancer-related signaling networks where vesicle transport contributes to receptor availability and pathway crosstalk.
Synip CRISPR/Cas9 KO Plasmid (h) is a pool of plasmids designed for targeted disruption of the STXBP4 gene in human cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the STXBP4 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 STXBP4 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 Synip protein expression.
This CRISPR knockout system enables efficient generation of STXBP4-deficient cell models for investigation of Synip signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by Synip CRISPR/Cas9 KO Plasmid (h) and Synip CRISPR/Cas9 KO Plasmid (h2) target distinct sites within the STXBP4 locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by Synip HDR Plasmid (h) and Synip HDR Plasmid (h2) contain a puromycin resistance cassette and an RFP reporter flanked by STXBP4 homology arms to support homology-directed repair at defined STXBP4 target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
