Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

ADP-ribosylation factor is functionally and physically associated with the Golgi complex.

Stearns T, Willingham MC, Botstein D, Kahn RA

ADP-ribosylation factor (ARF) is a ubiquitous, highly conserved 21-kDa GTP-binding protein, first identified in animal cells as the cofactor required for the in vitro ADP-ribosylation of the stimulatory regulatory subunit of adenylate cyclase, Gs, by cholera toxin. As the relevance of this activity to in vivo function is unknown, we have taken advantage of the conserved nature of ARF to ... [more]

Co-crystal Structure

Interaction directly demonstrated at the atomic level by X-ray crystallography. Also used for NMR or Electron Microscopy (EM) structures. If there is no obvious bait-hit directionality to the interaction involving 3 or more proteins, then the co-crystallized proteins should be listed as a complex.
