Two active states of the Ras-related Bud1/Rsr1 protein bind to different effectors to determine yeast cell polarity.

Park HO, Bi E, Pringle JR, Herskowitz I

Cells of budding yeast organize their cytoskeleton in a highly polarized manner during vegetative growth. Selection of a site for polarization requires a group of proteins including a Ras-like GTPase, Bud1, and its regulators. Another group of proteins, which includes a Rho-like GTPase (Cdc42), its guanine nucleotide exchange factor (Cdc24), and Bem1, is necessary for organization of the actin cytoskeleton ... [more]

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.

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.
