**作者**:

Zhang Y. et al. (2009)

**摘要**:

本研究通过质谱分析鉴定了Ksr1的Ser392磷酸化位点,并发现其响应Ras激活后的磷酸化动态变化。使用Phospho-Ser392特异性抗体验证了该位点磷酸化对ERK信号通路的调控作用,证明其通过影响Ksr1与MEK/ERK复合物的结合来增强信号传递。

**作者**:

Roy F. et al. (2015)

**摘要**:

研究揭示了Ksr1的Ser392磷酸化在黑色素瘤转移中的双重作用。通过Phospho-Ser392抗体检测发现,该位点磷酸化水平与Akt活性呈负相关,表明Ksr1可能通过此磷酸化事件抑制PI3K-Akt通路,从而调控肿瘤细胞侵袭性。

**摘要**:

利用Phospho-Ser392抗体进行亚细胞定位分析,发现Ksr1在Ser392磷酸化后从细胞质转位至细胞膜,促进Raf-MEK-ERK信号体的组装。研究证明该磷酸化事件是Ras信号时空动态调控的关键分子开关。

背景信息

The Ksr-1 (Kinase Suppressor of Ras-1) protein is a conserved scaffold component of the Ras/MAPK (mitogen-activated protein kinase) signaling pathway, which regulates critical cellular processes such as proliferation, differentiation, and survival. Phosphorylation at Ser392 is a key post-translational modification that modulates Ksr-1's function. This phosphorylation event, often mediated by upstream kinases like C-TAK1. influences Ksr-1's subcellular localization, stability, or interaction with other signaling molecules (e.g., Raf, MEK, ERK), thereby fine-tuning MAPK pathway activation. The Ksr-1 (Phospho-Ser392) antibody specifically detects this phosphorylated form, enabling researchers to study the activation status and regulatory mechanisms of Ksr-1 in various contexts. It is widely used in applications like Western blotting, immunofluorescence, or immunohistochemistry to investigate Ras/MAPK signaling dynamics in diseases such as cancer, where pathway dysregulation is common. This antibody also aids in exploring therapeutic strategies targeting Ksr-1 or its associated signaling nodes. Validation typically includes testing in knockout models or phosphorylation-blocking assays to ensure specificity for Ser392-phosphorylated Ksr-1.
