Mammalian Amino Acid Transport System y + Revisited: Specificity and Cation Dependence of the Interaction with Neutral Amino Acids

Journal of Membrane Biology, 1999
A reevaluation of the specificity of system y+, the classical transporter for cationic amino acids is presented. System y+ has been defined as a transporter for cationic amino acids that binds neutral amino acids with lower affinity in the presence of Na+.

Plasma membrane clustering of system y+ (CAT-1) amino acid transporter as detected by immunohistochemistry

American Journal of Physiology-Endocrinology and Metabolism, 1994
Transport of cationic amino acids in fully differentiated mammalian cells is mediated primarily by system y1+ [cationic amino acid transporter (CAT)-1 gene product]. Antibodies, prepared against synthetic peptide sequences predicted to be extracellular loops of the CAT-1 transporter protein, detected the transporter on the surface of cultured cells. In

Identification of the Cationic Amino Acid Transporter (System y+) of the Rat Blood‐Brain Barrier

Journal of Neurochemistry, 1993
Abstract: Cationic amino acids are transported from blood into brain by a saturable carrier at the blood‐brain barrier (BBB). The transport properties of this carrier were examined in the rat using an in situ brain perfusion technique. Influx into brain via this system was found to be sodium independent and followed Michaelis‐Men‐ten kinetics with ...

Cationic amino acid transport through system y+L in erythrocytes of patients with lysinuric protein intolerance

Pflügers Archiv, 2000
We test the hypothesis that lysinuric protein intolerance (LPI), a rare autosomal recessive defect of cationic amino acid transport, results from the absence of the recently described y+L amino acid transporter. We compare fluxes of lysine (1 microM) into erythrocytes of normal subjects with those of patients homozygous for the LPI mutation.

Y+- and L-system amino acid transport in normal and chronic lymphocytic leukemia lymphocytes: Photoinhibition by fluoronitrophenylazide

Archives of Biochemistry and Biophysics, 1985
Three major pathways mediate amino acid transport into mammalian cells: the A-system and the ASC-system, which require a sodium gradient across the plasma membrane, and the L-system, which has no requirement for a sodium gradient. We have found that the lymphocytes from patients with B-cell chronic lymphocytic leukemia (CLL) have a marked reduction in ...
