描述：

NIK Antibody能够检测内源NIK蛋白总体水平。此多克隆抗体是通过合成人源对应的NIK gly659位点周围的肽段来免疫动物而获得。抗体是通过protein A和多肽亲和层析纯化。核因子κ B(NF-κB)/Rel 家族的转录调控因子在炎症反应和免疫反应中发挥了至关重要的作用(1,2)。在哺乳动物中一共有5个家族成员: RelA, c-Rel, RelB, NF-κB1 (p105/p50) 和 NF-κB2 (p100/p52)。 p105 和 p100 在蛋白水解酶的作用下分别形成p50 和 p52。Rel与p50和p52形成二聚体，此复合体能够结合到DNA上调控转录。在未刺激的状态下， NF-κB 在IκB抑制剂作用下在细胞质中处于非活性状态(3-5)。 NF-κB激活因子能够诱导 IκB 蛋白的磷酸化, 这就使IκB能够快速的经过泛素化-蛋白酶通路降解从而释放 NF-κB，激活的NF-κB入核调控基因的表达(6-8)。 NIK 和 IKKα (IKK1) 调节磷酸化并促使NF-κB2 (p100) 生成p52, p52之后会入核发挥功能(9-11)。NF-kB诱导激酶(NIK)能够控制NF-kappaB的激活,NIK是 MAP3K家族的一员，最初是被鉴定为TRAF2互作蛋白并能结合到受体上而激活(12)。NIK 形成复合体并磷酸化IKK1和IKK2, 从而导致磷酸化IkappaB 使得NF-kappaB入核(13-15)。

Homology

Species predicted to react based on 100% sequence homology: Rat, Monkey, Bovine, Horse

Specificity / Sensitivity

NIK Antibody detects endogenous levels of total NIK protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues adjacent to glycine 659 of human NIK. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Transcription factors of the nuclear factor κ B (NF-κB)/Rel family play a pivotal role in inflammatory and immune responses (1,2). There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which is then translocated to the nucleus (9-11).Activation of NF-kappaB can be controlled by NF-kB-inducing kinase (NIK), a member of the MAP3K family that was originally identified as a TRAF2-interacting protein and thereby coupled to receptor activation (12). NIK forms a complex with and phosphorylates IKK1 and IKK2, subsequently leading to the phosphorylation of IkappaB and translocation of NF-kappaB to the nucleus (13-15).
