Protein
Lysine histidine transporter 2
Organism
Arabidopsis thaliana
Function
Amino acid-proton symporter. Transporter with a broad specificity for neutral and acidic amino acids. Basic amino acids are only marginally transported. Involved in import of amino acids into the tapetum cells for synthesis of compounds important for microspore structure.
Similarity
Belongs to the amino acid/polyamine transporter 2 family. Amino acid/auxin permease (AAAP) (TC 2.A.18.2) subfamily.
