Affinity Capture-Western

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins.

Elimination of C/EBPalpha through the ubiquitin-proteasome system promotes the development of liver cancer in mice.

Wang GL, Shi X, Haefliger S, Jin J, Major A, Iakova P, Finegold M, Timchenko NA

Despite significant advancements in our understanding of cancer development, the molecular mechanisms that underlie the formation of liver cancer remain largely unknown. C/EBPalpha is a transcription factor that regulates liver quiescence. Phosphorylation of C/EBPalpha at serine 193 (S193-ph) is upregulated in older mice and is thought to contribute to age-associated liver dysfunction. Because development of liver tumors is associated with ... [more]
