生物活性:人Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9)是一种分泌性枯草酶,属于蛋白酶K亚家族。PCSK9是作为一种可溶性酶合成的,它通过非共价相互作用,在ER、前结构域和成熟链共同分泌过程中进行自催化的分子内加工。PCSK9与低密度脂蛋白受体(LDLR)结合,并在胆固醇稳态中发挥重要的调节作用。通过阻止PCSK9/LDLR相互作用来抑制PCSK9功能,目前正在探索作为一种降低胆固醇水平的方法。PCSK9也与载脂蛋白受体2 (ApoER2)结合,并在神经发育中发挥作用。

Recombinant Human DPP4/CD26 (Mammalian, C-6His)
DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. |
