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.

Spliceosome disassembly catalyzed by Prp43 and its associated components Ntr1 and Ntr2.

Two novel yeast splicing factors required for spliceosome disassembly have been identified. Ntr1 and Ntr2 (NineTeen complex-Related proteins) were identified for their weak association with components of the Prp19-associated complex. Unlike other Prp19-associated components, these two proteins were primarily associated with the intron-containing spliceosome during the splicing reaction. Extracts depleted of Ntr1 or Ntr2 exhibited full splicing activity, but accumulated ... [more]
