Protein
Large neutral amino acids transporter small subunit 1
Gene
SLC7A5, CD98LC, LAT1, MPE16
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Sodium-independent, high-affinity transport of large neutral amino acids such as phenylalanine, tyrosine, leucine, arginine and tryptophan, when associated with SLC3A2/4F2hc. Involved in cellular amino acid uptake. Acts as an amino acid exchanger. Involved in the transport of L-DOPA across the blood-brain barrier, and that of thyroid hormones triiodothyronine (T3) and thyroxine (T4) across the cell membrane in tissues such as placenta. Plays a role in neuronal cell proliferation (neurogenesis) in brain. Involved in the uptake of methylmercury (MeHg) when administered as the L-cysteine or D,L-homocysteine complexes, and hence plays a role in metal ion homeostasis and toxicity. Involved in the cellular activity of small molecular weight nitrosothiols, via the stereoselective transport of L-nitrosocysteine (L-CNSO) across the transmembrane. May play an important role in high-grade gliomas. Mediates blood-to-retina L-leucine transport across the inner blood-retinal barrier which in turn may play a key role in maintaining large neutral amino acids as well as neurotransmitters in the neural retina. Acts as the major transporter of tyrosine in fibroblasts.14 Publications

Miscellaneousi

Miscellaneous

The uptake of leucine, tyrosine and tryptophan is inhibited by the different iodothyronines, in particular T3. Leucine transport is also inhibited by small zwitterionic amino acids (i.e. glycine, alanine, serine, threonine and cysteine) and by glutamine and asparginine. The uptake of T3 is almost completely blocked by coincubation with leucine, tryptophan, tyrosine, and phenylalanine, or 2-amino-bicyclo-(2,2,1)-heptane-2-carboxylate (BCH). Methionine uptake was inhibited by the L-system substrates L-leucine, BCH, L-cysteine and by the MeHg-L-cysteine complex and structurally related S-ethyl-L-cysteine. MeHg-L-cysteine uptake is inhibited by L-methionine, L-leucine, BCH and S-ethyl-L-cysteine. L-leucine uptake was inhibited by L-CNSO. Tyrosine uptake in fibroblasts was inhibited by D-methionine, and methyl-aminoisobutyric acid (MeAIB).
