Protein
Amino acid permease 4
Organism
Arabidopsis thaliana
Function
Amino acid-proton symporter. Stereospecific transporter with a broad specificity for neutral amino acids, favoring small amino acids such as alanine, asparagine and glutamine. Accepts also large aromatic residues such as in phenlalanine or tyrosine.
Similarity
Belongs to the amino acid/polyamine transporter 2 family. Amino acid/auxin permease (AAAP) (TC 2.A.18.2) subfamily.
