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.

Corepressor CtBP1 interacts with and specifically inhibits CBP activity.

Senyuk V, Sinha KK, Nucifora G

Transcription repression in eukaryotes is mediated by a wide variety of transcription factors that usually recruit corepressors and form corepressor complexes at the specific promoter sites. One of these corepressors is the C-terminal-binding protein (CtBP) which was first identified as a protein that binds to the C-terminal region of the adenovirus E1A protein. CtBP has a strong role in both ... [more]
