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.

Centromere proteins Cenpa, Cenpb, and Bub3 interact with poly(ADP-ribose) polymerase-1 protein and are poly(ADP-ribosyl)ated.

Saxena A, Saffery R, Wong LH, Kalitsis P, Choo KH

Poly(ADP-ribose) polymerase-1 (PARP-1) is activated by DNA strand breaks during cellular genotoxic stress response and catalyzes poly(ADP-ribosyl)ation of acceptor proteins. These acceptor proteins include those involved in modulation of chromatin structure, DNA synthesis, DNA repair, transcription, and cell cycle control. Thus, PARP-1 is believed to play a pivotal role in maintaining genome integrity through modulation of protein-protein and protein-DNA interactions. ... [more]

An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.
