CC -!- FUNCTION: The heterodimer with SLC3A2 functions as sodium-independent,
CC high-affinity transporter that mediates uptake of large neutral amino
CC acids such as phenylalanine, tyrosine, L-DOPA, leucine, histidine,
CC methionine and tryptophan (PubMed:9915839, PubMed:11011012). Functions
CC as an amino acid exchanger (By similarity). May play a role in the
CC transport of L-DOPA across the blood-brain barrier (Probable). May act
CC as the major transporter of tyrosine in fibroblasts (By similarity).
CC May mediate blood-to-retina L-leucine transport across the inner blood-
CC retinal barrier (By similarity). Can mediate the transport of thyroid
CC hormones triiodothyronine (T3) and thyroxine (T4) across the cell
CC membrane. When associated with LAPTM4B, the heterodimer formed by
CC SLC3A2 and SLC7A5 is recruited to lysosomes to promote leucine uptake
CC into these organelles, and thereby mediates mTORC1 activation. Involved
CC in the uptake of toxic methylmercury (MeHg) when administered as the L-
CC cysteine or D,L-homocysteine complexes. Involved in the cellular
CC activity of small molecular weight nitrosothiols, via the
CC stereoselective transport of L-nitrosocysteine (L-CNSO) across the
CC membrane (By similarity). {ECO:0000250|UniProtKB:Q01650,
CC ECO:0000250|UniProtKB:Q63016, ECO:0000269|PubMed:11011012,
CC ECO:0000269|PubMed:9915839, ECO:0000305|PubMed:11011012}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=25 uM for leucine {ECO:0000269|PubMed:9915839};
CC -!- SUBUNIT: Disulfide-linked heterodimer with the amino acid transport
CC protein SLC3A2/4F2hc (PubMed:9915839, PubMed:11011012). Interacts with
CC LAPTM4B; this recruits the heterodimer formed by SLC3A2 and SLC7A5 to
CC lysosomes to promote leucine uptake into these organelles and is
CC required for mTORC1 activation (By similarity).

CC ECO:0000269|PubMed:9915839}.
CC -!- SUBCELLULAR LOCATION: Apical cell membrane
CC {ECO:0000250|UniProtKB:Q01650}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:Q01650}. Cell membrane
CC {ECO:0000269|PubMed:9915839}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:Q01650}. Lysosome membrane
CC {ECO:0000250|UniProtKB:Q01650}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:Q01650}. Note=Located to the plasma membrane by
CC SLC3A2/4F2hc (PubMed:9915839). Localized to the apical membrane of
CC placental syncytiotrophoblastic cells. Recruited to lysosomes by
CC LAPTM4B (By similarity). Expressed in both luminal and abluminal
CC membranes of brain capillary endothelial cells (By similarity).
CC {ECO:0000250, ECO:0000250|UniProtKB:Q01650,
CC ECO:0000269|PubMed:9915839}.
CC -!- TISSUE SPECIFICITY: Detected in brain, spleen, liver and testis (at
CC protein level) (PubMed:9915839). Predominantly expressed in the
CC microvessels in the brain parenchyma of the central nervous system.
CC Also detected in the subfornical organ, the subcommissural organ,
CC ventromedial nucleus of the hypothalamus, subgranular zone of the
CC dentate gyrus in hippocampus, ependymal layer of the lateral
CC ventricles, and the olfactory bulb. Very strong expression also seen in
CC testis, ovary, and placenta with weaker expression in spleen, skin,
CC brain, thymus, stomach, lung, heart, kidney, small intestine, uterus
CC and skeletal muscle. {ECO:0000269|PubMed:10574970,
CC ECO:0000269|PubMed:11011012, ECO:0000269|PubMed:11117468,
CC ECO:0000269|PubMed:9915839}.
CC -!- DEVELOPMENTAL STAGE: Strong expression in the liver of 14 dpc embryo.
CC In embryo of 18 dpc expressed strongly in brain, moderate expression in
CC spleen and brain and weak expression in liver.
CC {ECO:0000269|PubMed:9915839}.
CC -!- INDUCTION: Expression induced by concanavalin-A stimulation.
CC {ECO:0000269|PubMed:9915839}.
CC -!- MISCELLANEOUS: Leucine uptake was inhibited by ileum, valine histidine
CC and phenylalanine as well as by 2-amino-bicyclo-(2,2,1)-heptane-2-
CC carboxylate (BCH) (a specific inhibitor of system L transport).
CC -!- SIMILARITY: Belongs to the amino acid-polyamine-organocation (APC)
CC superfamily. L-type amino acid transporter (LAT) (TC 2.A.3.8) family.
CC {ECO:0000305}.
