Affinity Capture-MS

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.

L2DTL/CDT2 interacts with the CUL4/DDB1 complex and PCNA and regulates CDT1 proteolysis in response to DNA damage.

Higa LA, Banks D, Wu M, Kobayashi R, Sun H, Zhang H

The CUL4 (cullin 4) proteins are the core components of a new class of ubiquitin E3 ligases that regulate cell cycle, DNA replication and DNA damage response. To determine the composition of CUL4 ubiquitin E3 ligase complex, we used anti-CUL4 antibody affinity chromatography to isolate the proteins that associated with human CUL4 complexes and identified them by mass-spectrometry. A novel ... [more]
