Dosage Lethality

A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Pib2 and EGO Complex are both required for activation of TORC1.

Varlakhanova NV, Mihalevic M, Bernstein KA, Ford MGJ

The TORC1 complex is a key regulator of cell growth and metabolism in Saccharomyces cerevisiae The vacuole-associated EGO Complex couples activation of TORC1 to the availability of amino acids, specifically glutamine and leucine. EGO Complex is also essential for reactivation of TORC1 following rapamycin-induced growth arrest and for its distribution on the vacuolar membrane. Pib2, a FYVE-containing PI3P-binding protein, is ... [more]
