背景信息

The NF-κB-p65 (Phospho-Thr254) antibody is a specialized tool used to detect the phosphorylated form of the p65 subunit (RelA) of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) transcription factor at threonine 254. NF-κB is a critical regulator of immune response, inflammation, cell survival, and proliferation. The p65 subunit plays a central role in mediating NF-κB signaling by translocating to the nucleus upon activation, where it binds DNA to regulate target gene expression. Phosphorylation at Thr254 is a post-translational modification associated with the nuclear localization and transcriptional activity of p65. This modification can be induced by various stimuli, including pro-inflammatory cytokines (e.g., TNF-α, IL-1β) or cellular stress, and is tightly regulated by kinases such as IKK (IκB kinase) complex components or other upstream signaling molecules.

The antibody is widely used in research to study NF-κB activation dynamics in diseases like cancer, autoimmune disorders, and chronic inflammation. It enables the detection of phosphorylated p65 in techniques such as Western blotting, immunofluorescence, and immunohistochemistry, helping to elucidate signaling pathways, drug mechanisms, or disease biomarkers. Specificity for the phosphorylated Thr254 residue ensures accurate assessment of NF-κB pathway activity in cellular or tissue samples. Studies utilizing this antibody contribute to understanding how dysregulated NF-κB signaling drives pathological processes, aiding in therapeutic development targeting this pathway.
