CC -!- FUNCTION: The heterodimer with SLC3A2 functions as a sodium-
CC independent, high-affinity transporter that mediates uptake of large
CC neutral amino acids such as phenylalanine, tyrosine, histidine, met
CC hionine, tryptophan, valine, isoleucine and alanine (By similarity).
CC The heterodimer with SLC3A2 mediates the uptake of L-DOPA and leucine
CC (PubMed:9915839, PubMed:11011012). Functions as an amino acid exchanger
CC (By similarity). May play a role in the transport of L-DOPA across the
CC blood-brain barrier (PubMed:11011012). May act as the major transporter
CC of tyrosine in fibroblasts (By similarity). May mediate blood-to-retina
CC L-leucine transport across the inner blood-retinal barrier (By
CC similarity). Can mediate the transport of thyroid hormones
CC diiodothyronine (T2), triiodothyronine (T3) and thyroxine (T4) across
CC the cell membrane. When associated with LAPTM4B, the heterodimer formed
CC by SLC3A2 and SLC7A5 is recruited to lysosomes to promote leucine
CC uptake into these organelles, and thereby mediates mTORC1 activation.
CC Involved in the uptake of toxic methylmercury (MeHg) when administered
CC as the L-cysteine or D,L-homocysteine complexes. Involved in the
CC cellular 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,
