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 Sec7 Arf-GEF Is Recruited to the trans-Golgi Network by Positive Feedback.

Richardson BC, McDonold CM, Fromme JC

Arf GTPases are key regulators of both retrograde and anterograde traffic at the Golgi complex. The Golgi-localized Arf activators, Arf-GEFs (guanine exchange factor) of the BIG/GBF family, are poorly understood in terms of both their regulatory and localization mechanisms. We have performed a detailed kinetic characterization of a functional Golgi Arf-GEF, the trans-Golgi network (TGN)-localized Sec7 protein from yeast. We demonstrate ... [more]

Additional Notes

  • figure 4. Interaction is enriched when Mg2+ is included in the buffer; the robust Arf1 interaction requires the HDS1 domain on Sec7.

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
