包括p65的磷酸化调节和p65的乙酰化调节、p53对转录的竞争性调节,gsk3β对转录的间接调节;nf-κb转录调节中的常见的激酶:pka(蛋白激酶a),msk1和msk2(分裂素和压力激活激酶 )。
The expression of p-IκBα, ΙκBα, p-p65, and p65 was examined …
In a recent study, the phosphorylation of p65 and degradation of IkBa, and also the upregulation of TNF-a in macrophages treated with BD serum, demonstrate the activation of the NF-kB signaling...
靶点解惑Plus | NF-κB p65, p62和 Nrf2信号通路详解,剖析氧化应 …
NF-κB p65 是NF-κB家族成员之一,NF-κB是一种多效性转录因子,几乎存在于所有细胞类型中,并参与许多生物学过程,例如炎症、免疫、分化、细胞生长、肿瘤发生和凋亡。 NF-κB受翻译后修饰和亚细胞区室化的各种机制以及与其他辅因子或共抑制因子的相互作用的控制。 p65-RelA是哺乳动物NF-κB家族的成员,该家族由5个亚基组成:p50-NF-κB1,p52-NF-κB2,c-Rel,p65-RelA和RelB。
Mechanisms of NF-κB p65 and strategies for therapeutic …
Hence, the NF-κB p65 signaling pathway has been a pivotal point for intense drug discovery and development. This review begins with an overview of p65-mediated signaling followed by discussion of strategies that directly target NF-κB p65 in the context of chronic inflammation. Keywords: NF-κB, inflammation, therapy.
经典信号通路总结——NF-κB信号通路 - 知乎 - 知乎专栏
NF-κB蛋白通常会由p65和p50形成同源/异源二聚体,在胞质中因与抑制蛋白IkB结合形成了三聚体复合物而处于失活状态。 当上游信号因子TNF结合到细胞膜表面受体后,受体构象改变并将信号传递给IKK激酶(IkB kinase)…
CLK2 mediates IκBα-independent early termination of NF-κB
2024年5月9日 · In this study, we show that IκBα-independent nuclear NF-κB termination occurs at the transcriptional level through inhibitory phosphorylation by CDC-like kinase 2 (CLK2). The phosphorylation of...
Frontiers | Overexpression of IκB⍺ modulates NF-κB activation of ...
We investigate the relationship between p65 and inhibitor-κB⍺ (IκBα) protein levels and dynamic properties of the system, and how this interaction impacts on the expression of key inflammatory genes. Using bacterial artificial chromosomes, we developed new cell models of IκB⍺-eGFP protein overexpression in a pseudo-native genomic context.

促炎细胞因子、脂多糖 (LPS) 、生长因子以及抗原受体激活一个 IKK 复合体(IKKβ、IKKα 和 NEMO),后者将 IκB 蛋白磷酸化。 IκB 磷酸化导致其自身泛素化以及蛋白酶体降解,释放 NF-κB/Rel 复合体。 活性 NF-κB/Rel 复合体进一步由翻译后修饰(磷酸化、乙酰化、糖基化)作用激活,并转运入胞核,在核内单独或联合其他转录因子,包括 AP-1、Ets 和 Stat,并共同诱导靶标基因表达。 在备选(或称为非经典)NF-κB 通路中,NF-κB2 p100/RelB 复合体在细胞浆中失活。
Phosphorylation of NF-kappaB and IkappaB proteins: implications …
Activation of NF-kappaB mainly occurs via IkappaB kinase (IKK)-mediated phosphorylation of inhibitory molecules, including IkappaBalpha. Optimal induction of NF-kappaB target genes also requires phosphorylation of NF-kappaB proteins, such as p65, within their transactivation domain by a variety of kinases in response to distinct stimuli.
