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 is identified by mass spectrometric methods.

Proteomic analysis of the 26S proteasome reveals its direct interaction with transit peptides of plastid protein precursors for their degradation.

Sako K, Yanagawa Y, Kanai T, Sato T, Seki M, Fujiwara M, Fukao Y, Yamaguchi J

The 26S proteasome is an ATP-dependent proteinase complex that is responsible for regulated proteolysis of polyubiquitinated proteins in eukaryotic cells. Here, we report novel 26S proteasome interacting proteins in Arabidopsis as revealed by LC-MS/MS analysis. We performed a two-step screening process that involved affinity purification of the 26S proteasome using Arabidopsis plants expressing a FLAG-tagged RPT2a subunit and partial purification ...
