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.

The U4/U6 recycling factor SART3 has histone chaperone activity and associates with USP15 to regulate H2B deubiquitination.

Post-translational modifications of histone proteins produce dynamic signals that regulate the structure and function of chromatin. Mono-ubiquitination of H2B in the histone tail (at K123 in yeast or K120 in humans) is a conserved modification that has been implicated in the regulation of transcription, replication, and DNA repair processes. In a search for direct effectors of ubH2B, we identified a ... [more]
