Measuring NF-κB Phosphorylation and Acetylation

Research output: Chapter in Book/Report/Conference proceedingChapter


Posttranslational modifications of NF-κB, including phosphorylation, acetylation, and methylation, have emerged as important regulatory mechanisms to control the transcriptional outcomes of this important transcription factor. These modifications work independently, sequentially or in combination to modulate the diverse biological functions of NF-κB in cancer and inflammatory response. Here, we describe some experimental methods to detect the in vitro and in vivo phosphorylation and acetylation of NF-κB, specifically focusing on the RelA subunit of NF-κB. These methods include labeling the phospho- or acetyl- groups with radioisotopes in vitro and immunoblotting with site-specific anti-phospho-serine or acetyl-lysine antibodies in culture cells and tissue samples.
