The 4F2 antigen heavy chain induces uptake of neutral and dibasic amino acids in Xenopus oocytes.

Expression cloning of a human renal cDNA that induces high affinity transport of L-cystine shared with dibasic amino acids in Xenopus oocytes.

A renal cDNA clone (rBAT) that induces system bo,+-like amino acid transport activity in Xenopus oocytes has recently been isolated (Bertran, J., Werner, A., Moore, M. L., Strange, G., Markovich, D., Biber, J., Testar, X., Zorzano, A., Palacín, and Murer, H. (1992) Proc. Natl. Acad. Sci. U.S.A. 89, 5601-5605). Here we show the isolation of a cDNA clone by screening a human kidney cortex cDNA li...

Transport of Neutral and Dibasic Amino Acids by Human Leukocytes: Absence of Defect in Cystinuria.

Structure, expression and regulation of the murine 4F2 heavy chain.

The murine 4F2 molecule is a 125 kilodalton disulfide-linked heterodimeric cell-surface glycoprotein which has been shown to be involved in the processes of cellular activation and proliferation (1). To elucidate the structure, expression, and regulation of the 4F2 molecule, a murine 4F2 heavy chain (4F2HC) cDNA has been isolated and structurally characterized. The murine 4F2HC is a 526 amino a...

Cystinuria: Defective Intestinal Transport of Dibasic Amino Acids and Cystine.

The clinical manifestations of cystinuria are localized to the urinary tract and result from the formation of cystine calculi. The findings of increased excretion of cystine, lysine, arginine, and ornithine in the urine at a time when the plasma levels of these amino acids were normal or low suggested to Dent and Rose (2) that a renal tu-1)ular reabsorptive site, shared by the involved amino ac...
