| 描述 | The NF-κB p65 Antibody Sampler Kit contains reagents to examine NF-κB p65/RelA phosphorylation at Ser276 and Ser536; acetylation at Lys310; and total p65 levels.The NF-κB p65 Antibody Sampler Kit 包含了测试在Ser276和Ser536位点磷酸化的NF-κB p65/RelA ; Lys310位点乙酰基化的p65/RelA ; 总p65蛋白水平。 |
| 目标/特异性 | The total NF-κB p65 antibodies recognize endogenous levels of p65 regardless of post-translational modification state such as phosphorylation or acetylation. The phospho-NF-κB p65 antibodies recognize endogenous levels of p65 only when phosphorylated at their indicated target residues. The Acetyl-NF-κB p65 (Lys310) (D2S3J) Rabbit mAb recognizes transfected levels of p65 only when acetylated at Lys310. |

| 背景 | 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).转录调控因子的核因子κ B(NF-κB)/Rel 家族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 : 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。p50 和 p52形成二聚体并结合Rel蛋白，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入核(9-11)。 |
