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.

HJURP binds CENP-A via a highly conserved N-terminal domain and mediates its deposition at centromeres.

Shuaib M, Ouararhni K, Dimitrov S, Hamiche A

The human histone H3 variant, CENP-A, replaces the conventional histone H3 in centromeric chromatin and, together with centromere-specific DNA-binding factors, directs the assembly of the kinetochore. We purified the prenucelosomal e-CENP-A complex. We found that HJURP, a member of the complex, was required for cell cycle specific targeting of CENP-A to centromeres. HJURP facilitated efficient deposition of CENP-A/H4 tetramers to ... [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.
