NPR1

serine/threonine protein kinase NPR1, L000001273, YNL183C
Protein kinase; stabilizes several plasma membrane amino acid transporters by antagonizing their ubiquitin-mediated degradation; phosphorylates Aly2p; negatively regulates Ldb19p-mediated endocytosis through phosphorylation of Ldb19p, which prevents its association with the plasma membrane; Npr1p activity is negatively regulated via phosphorylation by the TOR complex; NPR1 has a paralog, PRR2, that arose from the whole genome duplication

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain 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]
