    Scientific background

    LAT3, (L-type amino acid transporter 3) is an amino acid transporter that belongs to the system L family of membrane transporters.

    The system L transporter family consists of various transporter subtypes with different characteristics in substrate selectivity and transport properties. It is characterized by a Na+ independent transport and its inhibition by 2-aminobicyclo heptane-2-carboxylicacid (BCH).

    System L transporters are a major route to provide cells with branched-chain and aromatic amino acids. Transporters that belong to this family are present in the basolateral membrane of epithelial cells and play important roles in the absorption of amino acids through the epithelial cells of the small intestine and renal proximal tubules. They are essential in the permeation of amino acids through the blood–tissue barriers such as blood brain barrier and placenta barrier1.

    LAT3 consists of seven transmembrane domains with a relatively long extracellular loop with predicted N-linked glycosylation sites between transmembrane domains 1 and 2 and a long intracellular loop with several putative phosphorylation sites between transmembrane domains 6 and 72,3.

    LAT3 was shown to be up-regulated in prostate cancer and responsible for the increased uptake of leucine into the tumor cells. Hence, it is an appealing target for cancer therapy4.
