General annotation (Comments)

Function

Involved in the sodium-independent uptake of dibasic amino acids and sodium-dependent uptake of some neutral amino acids. Requires coexpression with SLC3A2/4F2hc to mediate the uptake of arginine, leucine and glutamine. Plays a role in nitric oxide synthesis via transport of L-arginine, and is involved in the transport of L-arginine in monocytes. Ref.1

Subunit structure

Disulfide-linked heterodimer with the amino acid transport protein SLC3A2/4F2hc By similarity. Ref.1

Subcellular location

Basolateral cell membrane; Multi-pass membrane protein By similarity.

Tissue specificity

Strongly expressed in kidney and intestine. Weaker expression observed in epididymis, testis, ovary, thyroid pancreas, sub-gland and liver. Ref.1

Sequence similarities

Belongs to the amino acid-polyamine-organocation (APC) superfamily. L-type amino acid transporter (LAT) (TC 2.A.3.8) family. [View classification]

Biophysicochemical properties

Kinetic parameters:

KM=91.5 µM for L-arginine (in the absence of NaCl) Ref.1

KM=340.8 µM for L-arginine (in the presence of 0.1 M NaCl)

KM=21.7 µM for L-leucine (in the presence of 0.1 M NaCl)

KM=1.36 mM for L-alanine (in the presence of 0.1 M NaCl)

KM=47.9 µM for L-leucine (in the presence of 0.1 M LiCl)
