BAIT

PHO89

ITN1, YBR296C
Plasma membrane Na+/Pi cotransporter; active in early growth phase; similar to phosphate transporters of Neurospora crassa; transcription regulated by inorganic phosphate concentrations and Pho4p; mutations in related human transporter genes hPit1 and hPit2 are associated with hyperphosphatemia-induced calcification of vascular tissue and familial idiopathic basal ganglia calcification

GST1, PNM2, SAL3, SUF12, SUP2, SUP36, translation termination factor GTPase eRF3, eRF3, [PSI(+)], [PSI], L000002200, YDR172W
Translation termination factor eRF3; has a role in mRNA deadenylation and decay; altered protein conformation creates the [PSI(+)] prion that modifies cellular fitness, alters translational fidelity by affecting reading frame selection, and results in a nonsense suppressor phenotype; many stress-response genes are repressed in the presence of [PSI(+)]

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.

Role of a ribosome-associated E3 ubiquitin ligase in protein quality control.

Bengtson MH, Joazeiro CA

Messenger RNA lacking stop codons ('non-stop mRNA') can arise from errors in gene expression, and encode aberrant proteins whose accumulation could be deleterious to cellular function. In bacteria, these 'non-stop proteins' become co-translationally tagged with a peptide encoded by ssrA/tmRNA (transfer-messenger RNA), which signals their degradation by energy-dependent proteases. How eukaryotic cells eliminate non-stop proteins has remained unknown. Here we ... [more]
