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.

Selective requirement of H2B N-Terminal tail for p14ARF-induced chromatin silencing.

Choi J, Kim H, Kim K, Lee B, Lu W, An W

The N-terminal tail of histone H2B is believed to be involved in gene silencing, but how it exerts its function remains elusive. Here, we report the biochemical characterization of p14ARF tumor suppressor as a transcriptional repressor that selectively recognizes the unacetylated H2B tails on nucleosomes. The p14ARF-H2B tail interaction is functional, as the antagonistic effect of p14ARF on chromatin transcription ... [more]
