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.

Ribosomal protein S7 is both a regulator and a substrate of MDM2.

MDM2 associates with ribosomal protein S7, and this interaction is required to inhibit MDM2's E3 ligase activity, leading to stabilization of MDM2 and p53. Notably, the MDM2 homolog MDMX facilitates the inhibition of MDM2 E3 ligase activity by S7. Further, ablation of S7 inhibits MDM2 and p53 accumulation induced by different stress signals in some cell types. Thus, ribosomal/nucleolar stress ... [more]
