产品描述
The mouse NF-κB subunit p65 ELISA kit is suitable for the quantitative determination of mouse p65 in different sample types, including serum, plasma, and tissue homogenates. This assay employs the bi-antibody sandwich technique and enzyme-substrate chromogenic reaction to quantify antigen levels in the sample. The amount of synthesized colored products is positively related to the analyte of interest in the sample.
p65, also called RELA, is a member of the NF-κB family of transcriptional regulatory proteins that works as the activating component of the p65/p50 heterodimer. It plays an essential role in cell survival as p65-deficient mice do not survive. Nuclear translocation of the p65/p50 heterodimer is essential for NF-κB signaling. On activation of TNFR1, the TRAF2/5 activates the IKK complex, resulting in IκBα phosphorylation and subsequent ubiquitin-dependent proteasomal degradation. This relieves the NF-κB p65/p50 heterodimer from cytosolic retention, leading to nuclear translocation and target gene activation. Acetylation of p65 affects its biological function. Acetylation on lysine residue 221 is crucial for DNA binding and for inhibiting the interaction between p65 and IκBα.
