| Standard Name | Npr1p 1 |
|---|---|
| Systematic Name | Ynl183cp |
| ORF Classification | Verified |
| Description | 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 (2, 3, 4, 5, 6) |
