POMC CRISPR/Cas9 KO Plasmid (r): sc-437377
- Target species: rat
- 20 µg of transfection-ready, purified plasmid DNA; Suitable for up to 20 transfections
- POMC CRISPR/Cas9 Knockout (KO) Plasmid (r) 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 POMC 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
- Following transfection, gene knockout efficiency can be assayed by WB, IF or IHC using antibody: ACTH/CLIP Antibody (F-3): sc-373878

Overview
Proopiomelanocortin (POMC) is a neuroendocrine prohormone precursor that is proteolytically processed into multiple bioactive peptides, including ACTH and melanocortins, which coordinate stress axis signaling, energy balance, pigmentation, and nociception. In rat hypothalamic and pituitary pathways, POMC-derived peptides act through melanocortin receptors and integrate nutrient and hormonal cues to regulate feeding behavior and metabolic homeostasis. POMC expression is tightly controlled by developmental and stimulus-responsive transcriptional programs, and altered POMC processing or signaling is implicated in obesity-related phenotypes, dysregulated HPA-axis responses, and endocrine dysfunction. As a central node in neuropeptide biosynthesis and GPCR-mediated signaling, POMC is widely used to study neuroendocrine cell identity, peptide maturation, and systemic physiology.
POMC CRISPR/Cas9 KO Plasmid (r) is a pool of plasmids designed for targeted disruption of the gene in rat cell lines. Each plasmid co-expresses a unique single guide RNA (sgRNA) targeting a distinct site within the 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 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 POMC protein expression.
This CRISPR knockout system enables efficient generation of -deficient cell models for investigation of POMC signaling, functional genomics studies, cancer biology research, and evaluation of therapeutic responses in human cell lines.

Design Variants
CRISPRs +/- HDRs
- gRNAs encoded by POMC CRISPR/Cas9 KO Plasmid (r) and POMC CRISPR/Cas9 KO Plasmid (r2) target distinct sites within the locus. One or both targeting designs may be available. See Related Products for availability.
- HDR donor constructs encoded by POMC HDR Plasmid (r) and POMC HDR Plasmid (r2) contain a puromycin resistance cassette and an RFP reporter flanked by homology arms to support homology-directed repair at defined target sites corresponding to the CRISPR/Cas9 KO designs. HDR donor availability may vary. See Related Products for availability.
