Amino-acid permease with broad substrate specificity (PubMed:21764911, PubMed:28028545). GAP2 is the only amino-acid permease with very broad substrate specificity, none of the other GAP permeases is able to transport such a variety of amino acids (PubMed:21764911, PubMed:28028545). GAP2 is also able to transport thialysine, and thus probably also lysine (PubMed:21764911). Functions as a sensor via detection of some amino acids including methionine, leading to a rapid activation of trehalase, a downstream target of PKA (PubMed:21764911).

Belongs to the amino acid-polyamine-organocation (APC) superfamily. YAT (TC 2.A.3.10) family.
