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.

Sumoylation of p68 and p72 RNA helicases affects protein stability and transactivation potential.

Mooney SM, Grande JP, Salisbury JL, Janknecht R

The p68 (DDX5) and p72 (DDX17) proteins are members of the DEAD-box (DDX) family of RNA helicases. We show that both p68 and p72 are overexpressed in breast tumors. Bioinformatical analysis revealed that the SUMO pathway is upregulated in breast tumors and that both p68 and p72 contain one consensus sumoylation site, implicating that sumoylation of p68 and p72 increases ...

An interaction is detected between two proteins using chemically reactive or photo-activatable cross-linking reagents that covalently link amino acids in close proximity, followed by mass spectrometry analysis to identify the linked peptides (reviewed in PMID 37406423, 37104977). Experiments may be carried with live cells or cell lysates in which all proteins are expressed at endogenous levels (e.g. PMID 34349018, 35235311) or with recombinant proteins (e.g., PMID 28537071).
