Affinity Capture-MS

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 is identified by mass spectrometric methods.

Npa1p, a component of very early pre-60S ribosomal particles, associates with a subset of small nucleolar RNPs required for peptidyl transferase center modification.

We have identified a novel essential nucleolar factor required for the synthesis of 5.8S and 25S rRNAs termed Npa1p. In the absence of Npa1p, the pre-rRNA processing pathway leading to 5.8S and 25S rRNA production is perturbed such that the C2 cleavage within internal transcribed spacer 2 occurs prematurely. Npa1p accumulates in the immediate vicinity of the dense fibrillar component ... [more]

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.
