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.

The mitotic phosphorylation of p54(nrb) modulates its RNA binding activity.

Bruelle C, Bedard M, Blier S, Gauthier M, Traish AM, Vincent M

The RNA-binding protein p54(nrb) is involved in many nuclear processes including transcription, RNA processing, and retention of hyperedited RNAs. In interphase cells, p54(nrb) localizes to the nucleoplasm and concentrates with protein partners in the paraspeckles via an interaction with the non-coding RNA Neat1. During mitosis, p54(nrb) becomes multiphosphorylated and the effects of this modification are not known. In the present ... [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.

Cross-Linking-MS (XL-MS)
Cross-Linking-MS (XL-MS)

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).
