Description
PNC-27 is a synthetic 32-amino-acid chimeric peptide originally developed by academic researchers at NYU School of Medicine and Weill Cornell Medical College (Ehrlich, Michl, and colleagues) as a research tool for p53 tumor suppressor protein-protein interaction studies. The peptide combines two functional domains: (1) a segment corresponding to p53 residues 12-26, which contains the HDM-2 (human double minute 2) binding recognition sequence — the region through which the p53 tumor suppressor interacts with its principal negative regulator HDM-2 — and (2) a membrane-residency peptide (MRP) segment adapted from HIV-1 gp41, which enables membrane insertion behavior in research models. The peptide has been extensively investigated in published academic research literature for HDM-2 protein-protein interaction pharmacology, membrane-active peptide chemistry, and p53 pathway cell biology research. This compound is offered strictly as a research tool for laboratory studies of p53/HDM-2 pathway biochemistry, protein-protein interaction pharmacology, and membrane-active peptide chemistry.
