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.

14-3-3 proteins play a role in the cell cycle by shielding cdt2 from ubiquitin-mediated degradation.

Dar A, Wu D, Lee N, Shibata E, Dutta A

Cdt2 is the substrate recognition adaptor of CRL4(Cdt2) E3 ubiquitin ligase complex and plays a pivotal role in the cell cycle by mediating the proteasomal degradation of Cdt1 (DNA replication licensing factor), p21 (cyclin-dependent kinase [CDK] inhibitor), and Set8 (histone methyltransferase) in S phase. Cdt2 itself is attenuated by SCF(FbxO11)-mediated proteasomal degradation. Here, we report that 14-3-3 adaptor proteins interact ... [more]
