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.

Dynamic and transient interactions of Atg9 with autophagosomes, but not membrane integration, are required for autophagy.

Orsi A, Razi M, Dooley HC, Robinson D, Weston AE, Collinson LM, Tooze SA

Autophagy is a catabolic process essential for cell homeostasis, at the core of which is the formation of double-membrane organelles called autophagosomes. Atg9 is the only known transmembrane protein required for autophagy and is proposed to deliver membrane to the preautophagosome structures and autophagosomes. We show here that mammalian Atg9 (mAtg9) is required for the formation of DFCP1-positive autophagosome precursors ... [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.

An interaction is inferred when a bait-enzyme fusion protein selectively modifies a vicinal protein with a diffusible reactive product, followed by affinity capture of the modified protein and identification by mass spectrometric methods.
