GNP1

glutamine permease GNP1, L000002806, YDR508C
High-affinity glutamine permease; also transports Leu, Ser, Thr, Cys, Met and Asn; expression is fully dependent on Grr1p and modulated by the Ssy1p-Ptr3p-Ssy5p (SPS) sensor of extracellular amino acids; GNP1 has a paralog, AGP1, that arose from the whole genome duplication

AGP1

YCC5, amino acid transporter AGP1, L000003271, YCL025C
Low-affinity amino acid permease with broad substrate range; involved in uptake of asparagine, glutamine, and other amino acids; expression regulated by SPS plasma membrane amino acid sensor system (Ssy1p-Ptr3p-Ssy5p); AGP1 has a paralog, GNP1, that arose from the whole genome duplication

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

Phosphorylation of a conserved Thr357 in yeast Nedd4-like ubiquitin ligase Rsp5 is involved in down-regulation of the general amino acid permease Gap1.

Sasaki T, Takagi H

Rsp5, an essential HECT-type ubiquitin ligase, is the only yeast Saccharomyces cerevisiae member of the Nedd4 family. Rsp5 triggers the ubiquitination-dependent endocytosis of the general amino acid permease Gap1 in response to a good nitrogen source. Previously, we showed that the Thr357Ala/Lys764Glu variant Rsp5 induces the constitutive inactivation of Gap1, which is mainly involved in uptake of the toxic proline ... [more]
