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.

BioID proximity mapping reveals novel SAP18 interactions in the prespliceosomal complex.

Kumari S, Adhikary A, Singh KK

SAP18 protein was originally discovered in association with the SIN3 transcriptional repressor complex. Subsequent biochemical fractionation studies identified SAP18 as a component of another distinct trimeric complex termed as the apoptosis- and splicing-associated protein (ASAP) complex. The existence of SAP18 in distinct complexes highlights its dual role in transcriptional and splicing regulation. In our study, we aim to define the ... [more]

Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.
