HOON pre-B leukaemia cell line.
Reacts with the heavy chain of the CD98 molecule. The epitope is distinct from clone 44H7 but the same as recognised by 4F2. This antibody binds to all cell lines in culture and to activated T-cells. Recommended Negative Controls: MOUSE IgG1 NEGATIVE CONTROL:FITC
Required for the function of light chain amino-acid transporters. Involved in sodium-independent high-affinity transport of large neutral amino acids such as phenylalanine tyrosine leucine arginine and tryptophan. Involved in guiding and targeting of LAT1 and LAT2 to the plasma membrane. When associated with SLC7A6 or SLC7A7 acts as an arginine/glutamine exchanger following an antiport mechanism for amino acid transport influencing arginine release in exchange for extracellular amino acids. Plays a role in nitric oxide synthesis in human umbilical vein endothelial cells (HUVECs) via transport of L-arginine. Required for normal and neoplastic cell growth. When associated with SLC7A5/LAT1 is also 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. 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. When associated with SLC7A5 or SLC7A8 involved in the cellular activity of small molecular weight nitrosothiols via the stereoselective transport of L-nitrosocysteine (L-CNSO) across the transmembrane. Together with ICAM1 regulates the transport activity LAT2 in polarized intestinal cells by generating and delivering intracellular signals. When associated with SLC7A5 plays an important role in transporting L-leucine from the circulating blood to the retina across the inner blood-retinal barrier.

Colocalizes with cadherins By similarity. Interacts with FAM57A/CT120 and ICAM1. Constitutively and specifically associates with beta-1 integrins (alpha-2/beta-1 alpha-3/beta-1 alpha-5/beta-1 and alpha-6/beta-1) but minimally with alpha-4/beta-1.

Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Localized to the plasma membrane when associated with SLC7A5 or SLC7A8. Localized to the placental apical membrane. Located selectively at cell-cell adhesion sites By similarity. Colocalized with SLC7A8/LAT2 at the basolateral membrane of kidney proximal tubules and small intestine epithelia. Expressed in both luminal and abluminal membranes of brain capillary endothelial cells By similarity. Ref. 16Ref. 17Ref. 20Ref. 23Ref. 26Ref. 40Ref. 32Ref. 33Tissue specificityExpressed ubiquitously in all tissues tested with highest levels detected in kidney placenta and testis and weakest level in thymus. During gestation expression in the placenta was significantly stronger at full-term than at the mid-trimester stage. Expressed in HUVECS and at low levels in resting peripheral blood T-lymphocytes and quiescent fibroblasts. Also expressed in fetal liver and in the astrocytic process of primary astrocytic gliomas. Expressed in retinal endothelial cells and in the intestinal epithelial cell line Caco2-BBE. Ref. 6Ref. 17Ref. 20Ref. 25Ref. 26Ref. 28Ref. 32Ref. 4Ref. 5Induction: Expression is induced in resting peripheral blood T-lymphocytes following PHA stimulation. Expression increases at the time of maximal DNA synthesis in fibroblasts stimulated to divide. Expression and the uptake of leucine is stimulated in mononuclear cytotrophoblast-like choriocarcinoma cells by combined treatment with PMA and calcium ionophore. Ref. 20Ref. 4Ref. 5Post-translational modificationPhosphorylation on Ser-406; Ser-408 or Ser-410 and on Ser-527 or Ser-531 by ecto-protein kinases favors heterotypic cell-cell interactions.
Arginine uptake is inhibited by increasing concentrations of leucine in the presence of Na+. Sequence similaritiesBelongs to the SLC3A transporter family.
