Broad substrate range permease which transports asparagine and glutamine with intermediate specificity. Also transports Ala, Cys, Gly, Ile, Leu, Met, Phe, Ser, Thr, Tyr and Val. Important for the utilization of amino acids as a nitrogen source. Induced by transcription factors DAL81 and STP1, which are activated by a signal initiated by the plasma membrane SPS (SSY1-PTR3-SSY5) amino acid sensor system in response to external amino acid levels. Palmitoylated by PFA4. Present with 21100 molecules/cell in log phase SD medium. Belongs to the amino acid-polyamine-organocation (APC) superfamily. YAT (TC 2.A.3.10) family.
