SN52（Cat No.:I044203）is a synthetic peptide inhibitor that selectively disrupts the interaction between the transcription factor NF-κB p65 subunit and its coactivator, importin α5 (also known as KPNA1). By blocking nuclear import of p65, SN52 effectively inhibits NF-κB–mediated gene transcription without affecting p50 or other nuclear import pathways. This specificity makes SN52 a valuable tool for studying NF-κB signaling in inflammation, cancer, and immune response. It enables researchers to dissect the role of p65-driven transcriptional activity in pathological contexts while minimizing off-target effects commonly associated with broad-spectrum NF-κB inhibitors.
