USP7 蛋白, Human (sf9)

The USP7 protein is a hydrolase that deubiquitinates multiple targets, including FOXO4, DEPTOR, KAT5, p53/TP53, MDM2, ERCC6, DNMT1, UHRF1, PTEN, KMT2E/MLL5, and DAXX. It cooperates with DAXX to enhance the E3 ligase activity of MDM2 and promote ubiquitination and degradation of p53/TP53. USP7 Protein, Human (sf9) is the recombinant human-derived USP7 protein, expressed by Sf9 insect cells , with tag free. The total length of USP7 Protein, Human (sf9) is 353 a.a., with molecular weight of ~41 kDa.

USP7 蛋白作为水解酶，在多种靶蛋白去泛素化中发挥着关键作用，包括 FOXO4、DEPTOR、KAT5、p53/TP53、MDM2、ERCC6、DNMT1、UHRF1、PTEN、KMT2E/MLL5 和 DAXX。它与 DAXX 合作，防止 MDM2 自身泛素化，并增强 MDM2 对 p53/TP53 的 E3 连接酶活性，促进 p53/TP53 泛素化和随后的降解。此外，USP7 参与早期胚胎发育过程中的细胞增殖、响应紫外线损伤的转录偶联核苷酸切除修复 (TC-NER) 以及 DNA 甲基化的维持。它调节染色质结构，表现出对“Lys-48”连接的泛素链的偏好，并调节生物钟。此外，USP7 有助于稳定参与糖异生、神经祖细胞维持和内体表面肌动蛋白聚合的特定蛋白质。重要的是，它的多样化功能凸显了它在细胞过程和微生物感染反应中的重要性，例如它在 HSV-1 感染期间参与疱疹病毒 1 反式作用转录蛋白 ICP0/VMW110 的稳定和反式激活。
