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.

DNA double-strand break (DSB) repair is initiated by MRE11 nuclease for both homology-directed repair (HDR) and alternative end joining (Alt-EJ). Here, we found that GRB2, crucial to timely proliferative RAS/MAPK pathway activation, unexpectedly forms a biophysically validated GRB2-MRE11 (GM) complex for efficient HDR initiation. GRB2-SH2 domain targets the GM complex to phosphorylated H2AX at DSBs. GRB2 K109 ubiquitination by E3 ... [more]

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.
