JAK1 蛋白, Human (sf9, His)

JAK1 protein is a non-receptor tyrosine kinase that plays a crucial role in IFN-α/β/γ signaling and serves as a kinase partner for IL-2 and IL-10 receptors. It cooperates with the type I interferon receptor IFNAR2 to phosphorylate and activate IFNAR2 upon interferon binding to IFNAR1-IFNAR2. JAK1 Protein, Human (sf9, His) is the recombinant human-derived JAK1 protein, expressed by sf9 insect cells , with N-His labeled tag. The total length of JAK1 Protein, Human (sf9, His) is 292 a.a., with molecular weight of 30-33 kDa.

多项研究证明，JAK1 蛋白是一种非受体酪氨酸激酶，在 IFN-α/β/γ 信号通路中发挥着至关重要的作用。它作为白细胞介素 (IL)-2 受体和 IL-10 受体的激酶伴侣，证明了其在不同细胞因子信号传导途径中的多功能性。此外，JAK1 作为 I 型干扰素受体 IFNAR2 的激酶伴侣，当干扰素与 IFNAR1-IFNAR2 异二聚体结合时，它会磷酸化并激活 IFNAR2，为 STAT 蛋白创建对接位点。JAK1 不仅直接磷酸化 STAT 蛋白，而且还通过反式激活与信号传导受体相关的其他 JAK 激酶来激活 STAT 信号传导。这种多方面的参与使 JAK1 成为复杂的信号通路网络中的核心角色，有助于免疫反应和细胞过程的调节。
