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.

Interplay between ribosomal protein S27a and MDM2 protein in p53 activation in response to ribosomal stress.

Sun XX, DeVine T, Challagundla KB, Dai MS

Ribosomal proteins play a critical role in tightly coordinating p53 signaling with ribosomal biogenesis. Several ribosomal proteins have been shown to induce and activate p53 via inhibition of MDM2. Here, we report that S27a, a small subunit ribosomal protein synthesized as an 80-amino acid ubiquitin C-terminal extension protein (CEP80), functions as a novel regulator of the MDM2-p53 loop. S27a interacts ... [more]

Throughput

  • Low Throughput

Additional Notes

  • MDM2 and p53 interacted with the ribosomal S27a protein in the co-immuniprecipitation experiment (Figure 2). The ubiquitin portion of the RPS27A cDNA was excluded in these experiments.
