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.

Publication

Mitochondrial functional interactions between frataxin and Isu1p, the iron-sulfur cluster scaffold protein, in Saccharomyces cerevisiae.

Ramazzotti A, Vanmansart V, Foury F

Friedreich's ataxia is caused by a deficit in the mitochondrial protein frataxin. The present work demonstrates that in vivo yeast frataxin Yfh1p and Isu1p, the mitochondrial scaffold protein for the Fe-S cluster assembly, have tightly linked biological functions, acting in concert to promote the Fe-S cluster assembly. A synthetic lethal screen on high iron media with the mild G107D yfh1 ... [more]

Affinity Capture-Western
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.

Co-crystal Structure
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.
