核因子 NF-KB 抑制劑 SN50 是轉錄因子 NF-KB 的細胞滲透性核易位抑制劑。它由介導該肽的細胞輸入的卡波西成纖維細胞生長因子 (K-FGF) 信號序列的疏水區(qū)(h 區(qū))和 NF-KB p50 亞基的核定位信號 (NLS) 組成。該肽抑制 LPS 或 TNF-α 刺激的鼠內(nèi)皮 LE-II 和人單核細胞 THP-1 細胞中 NF-KB 的核轉位。在幾個細胞系中,SN50 干擾了 NF-KB 介導的促凋亡事件,例如 caspase-3 激活。

Nuclear Factor NF-KB Inhibitor SN50 is a cell-permeable nuclear translocation inhibitor of the transcription factor NF-KB. It consists of the hydrophobic region (h-region) of the Kaposi fibroblast growth factor (K-FGF) signal sequence which mediates the cellular import of this peptide and the nuclear localization signal (NLS) of the NF-KB p50 subunit. The peptide inhibited nuclear translocation of NF-KB in LPS- or TNF-α-stimulated murine endothelial LE-II and human monocytic THP-1 cells. In several cell lines SN50 interfered with NF-KB-mediated pro-apoptotic events such as caspase-3 activation.
