Sodium-dependent neutral amino acid transporter B(0)AT1

Gene

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Transporter that mediates epithelial resorption of neutral amino acids across the apical membrane of epithelial cells in the kidney and intestine. It appears that leucine is the preferred substrate, but all large neutral non-aromatic L-amino acids bind to this transporter. Uptake of leucine is sodium-dependent. In contrast to other members of the neurotransmitter transporter family, does not appear to be chloride-dependent.1 Publication

Kineticsi

Vmax for leucine is about twice the value of Vmax for glutamine, and three times the value of Vmax for phenylalanine. KM and Vmax values are complex functions of the concentration of substrate (L-amino acid) and cosubstrate (Na+) and the membrane potential.

    Expressioni

    Tissue specificityi

    Expression observed in kidney, small intestine, and skin. Expression not observed in other organs, such as lung, skeletal muscle, brain, liver and pancreas. In kidney, expression is localized in the renal cortex but not in the medulla. Substantial amounts of expression in the proximal tubules. The distal nephron segments and the glomeruli are consistently negative. In the small intestine, expression is exclusively localized in villus enterocytes. High resolution of the hybridization-positive villi reveals a gradient of expression with the highest levels in apical cells. Not detected in crypt cells or in any other cell types of the small intestine.1 Publication
