生物活性

XMU-MP-10 is a selective NEDD4 inhibitor with a KD of 43.92 nM. XMU-MP-10 selectively inhibits NEDD4 auto-ubiquitination without affecting other ubiquitination activity, upregulates of β-TrCP and results YAP degradation without affecting NEDD4 protein expression. XMU-MP-10 exhibits significant in vivo efficacy in inhibiting TNBC tumor growth by enhancing CD8+ T cell infiltration. XMU-MP-10 enhances antitumor immune responses through the β-TrCP/YAP/ECM axis. XMU-MP-10 can be used for Triple-Negative Breast Cancer (TNBC) research[1].

体外研究
(In Vitro)

XMU-MP-10 与 NEDD4 的 HECT 结构域在 Y604、Y605 和 Y634 残基处发生相互作用[1]
XMU-MP-10 (0.1-10000 μM) 特异性结合野生型 NEDD4,但不结合 Y604A、Y605A 或 Y634A 位点突变的 NEDD4 突变体[1]
XMU-MP-10 (0.25-10 μM, 1-12 h) 以剂量依赖的方式显著抑制 NEDD4 的多聚泛素化,上调 β-TrCP 并导致 YAP 降解,此过程具有剂量和时间依赖性,且在 EMT6、4T1、MDA-MB-231 和 HCC38 细胞中不影响 NEDD4 蛋白的表达[1]
XMU-MP-10 (2-10 μM, 4 h) 在 HEK-293T 细胞中选择性抑制 NEDD4 的自泛素化,而不影响其他被测 E3 连接酶的泛素化活性[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
