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.

The NHR1-1 of Prs1 and the pentameric motif 284KKCPK288 of Prs3 permit multi-functionality of the PRPP synthetase in Saccharomyces cerevisiae.

The five-membered PRS gene family of Saccharomyces cerevisiae is an example of gene duplication allowing the acquisition of novel functions. Each of the five Prs polypeptides is theoretically capable of synthesising PRPP but at least one of the following heterodimers is required for survival: Prs1/Prs3, Prs2/Prs5 and Prs4/Prs5. Prs3 contains a pentameric motif 284KKCPK288 found only in nuclear proteins. Deletion ... [more]

Affinity Capture-MS

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 is identified by mass spectrometric methods.

PCA

A Protein-Fragment Complementation Assay (PCA) is a protein-protein interaction assay in which a bait protein is expressed as fusion to one of the either N- or C- terminal peptide fragments of a reporter protein and prey protein is expressed as fusion to the complementary N- or C- terminal fragment of the same reporter protein. Interaction of bait and prey proteins bring together complementary fragments, which can then fold into an active reporter, e.g. the split-ubiquitin assay.
