靶点详情

  • 最新研究进展：
    SERPINA4，又称为Kallistatin，是一种抗凝血和抗炎蛋白质。最新研究表明，Kallistatin可能对肺部疾病、心血管疾病、炎症等具有保护作用。
  • 功能：
    Inhibits human amidolytic and kininogenase activities of tissue kallikrein. Inhibition is achieved by formation of an equimolar, heat- and SDS-stable complex between the inhibitor and the enzyme, and generation of a small C-terminal fragment of the inhibitor due to cleavage at the reactive site by tissue kallikrein.
