  • 最新研究进展:
    CPB2(Carboxypeptidase B2)是一种胰高血糖素样酶,可以剪切肽链上的C端氨基酸。CPB2在血液凝血、纤溶调节和肾素-血管紧张素系统等生理过程中发挥重要作用。最近的研究表明,CPB2与一些肿瘤的发生和发展相关。例如,在乳腺癌和肺癌患者中,CPB2的过表达与肿瘤的恶性程度密切相关。因此,CPB2被认为是可能的肿瘤标志物。
     
  • 功能:
    Cleaves C-terminal arginine or lysine residues from biologically active peptides such as kinins or anaphylatoxins in the circulation thereby regulating their activities. Down-regulates fibrinolysis by removing C-terminal lysine residues from fibrin that has already been partially degraded by plasmin.
