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.
Publication
Mdm2 and PCAF increase Chk2 ubiquitination and degradation independently of their intrinsic E3 ligase activities.
We have previously shown that Chk2 stability, which is increased after DNA damage in some cells, is regulated in part through phosphorylation at S456 and that a mutant Chk2 (S456A) is hyperubiquitinated and turned over more rapidly than wild-type Chk2.(1) Here we show that the S456A mutant preferentially binds to Mdm2 compared to wild-type Chk2 and downregulation of Mdm2 with ...
