The non-canonical NF-κB pathway is an important arm of NF-κB signaling that predominantly targets activation of the p52/RelB NF-κB complex. This pathway depends on the inducible processing of p100, a molecule functioning as both the precursor of p52 and a RelB-specific inhibitor. A central signaling component of the non-canonical pathway is NF-κB-inducing kinase (NIK), which integrates signals from a subset of TNF receptor family members and activates a downstream kinase, IκB kinase-α (IKKα), for triggering p100 phosphorylation and processing. A unique mechanism of NIK regulation is through its fate control: the basal level of NIK is kept low by a TRAF-cIAP destruction complex and signal-induced non-canonical NF-κB signaling involves NIK stabilization. Tight control of the fate of NIK is important, since deregulated NIK accumulation is associated with lymphoid malignancies.
非经典 NF-κB 通路是 NF-κB 信号转导的一个重要分支，主要靶向 p52/RelB NF-κB 复合物的激活。该通路依赖于 p100 的诱导加工，p100 分子既是 p52 的前体，也是 RelB 特异性抑制剂。非经典通路的一个核心信号成分是 NF-κB 诱导激酶 (NIK)，它整合了 TNF 受体家族成员的一部分信号，并激活下游激酶 IκB 激酶-α (IKKα)，以触发 p100 磷酸化和加工。NIK 调节的一个独特机制是通过其命运控制：TRAF-cIAP 破坏复合物将 NIK 的基础水平保持在较低水平，信号诱导的非经典 NF-κB 信号转导涉及 NIK 稳定。NIK 命运的严格控制很重要，因为 NF-κB 信号转导涉及 NIK 稳定。NIK 积累失调与淋巴恶性肿瘤有关。
