IκB kinase - Wikipedia
In enzymology, an IκB kinase (EC 2.7.11.10) is an enzyme that catalyzes the chemical reaction: Thus, the two substrates of this enzyme are ATP and IκB protein, whereas its two products are ADP and IκB phosphoprotein.
IκB - 百度百科
IκB(inhibitor of NF-κB),是核因子κB(NF-κB)的抑制蛋白。 IκB家族由8个成员组成,分别是:p100、p105、IκBα、IκBβ、IκBγ、IκBε、Bcl-3和IκB-R,大部分IκB的 C端 含有3~8个 锚蛋白 重复 基序,并通过该基序与NF-κB结合,覆盖其Rel同源结构域的 核定位序列 (NLS),抑制NF-κB的活性。 IκB的 N端 是信号反应区,包含 丝氨酸 磷酸化和泛素化位点,在IκB的诱导降解中发挥重要作用。 在 静息状态 下,IκB-α与NF-κB p65、p50两个 亚单位 以 失活 状态存在于 细胞质 …
The IκB kinase complex: master regulator of NF-κB signaling
We describe here how these studies have identified a unique inhibitor of pro-inflammatory NF- κ B signaling, an unforeseen role for IKK α in the classical NF- κ B pathway, and a novel functional domain in IKK β that is not present in IKK α.
IκB 激酶 - 百度百科
IκB 激酶(IκB kinase;IKK)是一个生物化学与分子生物学名词。 一种丝氨酸特异的蛋白激酶,由多组分构成。 可被细胞外刺激激活、催化IκB (NF-κB的抑制蛋白)特异位点的磷酸化,导致IκB泛素化而被26S蛋白酶体降解,从而破坏IκB与NF-κB复合体,所释放的NF-κB进入细胞核,启动受其调节的基因转录。 IκB 激酶(IκB kinase;IKK)是一个生物化学与分子生物学名词。
IκB kinase β (IKKβ): Structure, transduction mechanism, biological ...
Inhibitory kappa B kinase beta (IKKβ), known as IKK2, is a key regulatory kinase responsible for the activation of NF-κB through its phosphorylation at Ser177 and Ser181 to promote the phosphorylation of inhibitors of kappa B (IκBs), triggering their ubiquitination and degradation to active the nuclear factor kappa-B (NF-κB) cascade.
The IKK Complex, a Central Regulator of NF-κB Activation
New work reveals the roles of the three subunits of IKK and how it is regulated. NF-κB represents a family of transcription factors that are normally kept inactive in the cytoplasm through interaction with inhibitory molecules of the IκB family.
NF-κB, IκB, and IKK: Integral components of immune system signaling
2019年10月19日 · Control over the immune cell functions of NF-κB results from signaling through one of two different routes: the canonical and noncanonical NF-κB signaling pathways. Present at the end of both...

In the present chapter, we review the structural information available on NF-κB, IκB, and IKK, the critical terminal components of the NF-κB signaling, in relation to their physiological function. Keywords: IKK (IκB kinase); IκB (inhibitor of NF-κB); NF-κB (nuclear factor κB); Signal transduction; Transcription factor.
IκB 激酶 β (IKKβ):结构、转导机制、生物学功能及其抑制剂的发现 …
抑制性 kappa B 激酶 beta (IKKβ),称为 IKK2,是一种关键的调节激酶,通过其 Ser177 和 Ser181 磷酸化来激活 NF-κB,从而促进 kappa B 抑制剂 (IκB) 的磷酸化,触发其泛素化和降解以激活核因子 kappa-B (NF-κB) 级联。 化学抑制IKKβ或其基因敲除已成为阻断NF-κB介导的肿瘤细胞增殖和迁移以及炎症反应的有效方法。 在这篇综述中,我们总结了IKKβ的结构特征和转导机制,以及从自然资源(如倍半萜类、二萜类、三萜类、黄酮类和生物碱类)和化学合成类(如嘧啶类、吡啶类 …
