Summary: Enables L-proline transmembrane transporter activity; beta-alanine transmembrane transporter activity; and polyamine transmembrane transporter activity. Involved in amino acid transport and polyamine transport. Located in cytoplasmic vesicle; fungal-type vacuole lumen; and plasma membrane. Human ortholog(s) of this gene implicated in retinitis pigmentosa 68. Orthologous to several human genes including SLC7A1 (solute carrier family 7 member 1); SLC7A14 (solute carrier family 7 member 14); and SLC7A2 (solute carrier family 7 member 2).

Nutrient transceptors physically interact with the yeast S6/protein kinase B homolog, Sch9, a TOR kinase target.
Title: Nutrient transceptors physically interact with the yeast S6/protein kinase B homolog, Sch9, a TOR kinase target.
Using in silico analyses and mutational studies we found that the C-terminal sequences of Gap1, Bap2, Hip1, Tat1, Tat2, Mmp1, Sam3, Agp1, and Gnp1 are about 50 residues long, associate with the Plasma Membrane , and have features that discriminate them from the termini of organellar amino acid transporters
Title: A Plasma Membrane Association Module in Yeast Amino Acid Transporters.
The results presented here suggest some possible synergistic effects of phosphorylated Alp1, Gap1 and Can1 amino acid permeases on regulation of amino acid utilization and metabolism in Saccharomyces cerevisiae.
Title: Effects of three permeases on arginine utilization in Saccharomyces cerevisiae.
results support the concept that different substrates bind to partially overlapping binding sites in the same general substrate-binding pocket of Gap1, triggering divergent conformations, resulting in different conformation-induced downstream processes
Title: Specific analogues uncouple transport, signalling, oligo-ubiquitination and endocytosis in the yeast Gap1 amino acid transceptor.
Although the Bul proteins mediate Gap1 ubiquitylation of two possible lysines, Lys-9 and Lys-16, the Aly proteins promote ubiquitylation of the Lys-16 residue only. This stress-induced pathway of Gap1 down-regulation targets other permeases as well.
Title: Stress conditions promote yeast Gap1 permease ubiquitylation and down-regulation via the arrestin-like Bul and Aly proteins.
study show that Gap1 and Can1 permeases undergo ubiquitin-dependent endocytosis in response to their substrates and that this endocytosis is due to transport catalysis rather than intracellular substrate accumulation.
Title: Substrate-induced ubiquitylation and endocytosis of yeast amino acid permeases.
a possible mechanism involved in the regulation of Rsp5 activity for Gap1 down-regulation via the phosphorylation of a conserved Thr357 in the Nedd4 family is proposed
Title: Phosphorylation of a conserved Thr357 in yeast Nedd4-like ubiquitin ligase Rsp5 is involved in down-regulation of the general amino acid permease Gap1.
Internal amino acids promote Gap1 permease ubiquitylation via TORC1/Npr1/14-3-3-dependent control of the Bul arrestin-like adaptors.

identified a self-propagating extrachromosomal circular DNA molecule that results from intrachromosomal recombination between long terminal repeats flanking GAP1
