Molecular Characterization of a Broad Selectivity Neutral Solute Channel*
- H. Tsukaguchi, C. Shayakul, +5 authors M. Hediger
- Chemistry, Medicine
- The Journal of Biological Chemistry
- 18 September 1998
In all living cells, coordination of solute and water movement across cell membranes is of critical importance for osmotic balance. The current concept is that these processes are of distinct… Expand
Molecular cloning and characterization of the vasopressin-regulated urea transporter of rat kidney collecting ducts.
- C. Shayakul, A. Steel, M. Hediger
- Biology, Medicine
- The Journal of clinical investigation
- 1 December 1996
Absorption of urea in the renal inner medullary collecting duct (IMCD) contributes to hypertonicity in the medullary interstitium which, in turn, provides the osmotic driving force for water… Expand
Cloning and characterization of the urea transporter UT3: localization in rat kidney and testis.
- H. Tsukaguchi, C. Shayakul, U. Berger, T. Tokui, D. Brown, M. Hediger
- Biology, Medicine
- The Journal of clinical investigation
- 1 April 1997
Urea transport in the kidney plays an important role in urinary concentration and nitrogen balance. Recently, three types of urea transporters have been cloned, UT1 and UT2 from rat and rabbit kidney… Expand
Novel AE1 mutations in recessive distal renal tubular acidosis. Loss-of-function is rescued by glycophorin A.
- V. Tanphaichitr, A. Sumboonnanonda, +5 authors S. Alper
- Biology, Medicine
- The Journal of clinical investigation
- 15 December 1998
The AE1 gene encodes band 3 Cl-/HCO3- exchangers that are expressed both in the erythrocyte and in the acid-secreting, type A intercalated cells of the kidney. Kidney AE1 contributes to urinary… Expand
Characterization of a Rat Na+-Dicarboxylate Cotransporter*
- X. Chen, C. Shayakul, U. Berger, W. Tian, M. Hediger
- Biology, Medicine
- The Journal of Biological Chemistry
- 14 August 1998
The metabolism of Krebs cycle intermediates is of fundamental importance for eukaryotic cells. In the kidney, these intermediates are transported actively into epithelial cells. Because citrate is a… Expand
Cloning and characterization of a potassium-coupled amino acid transporter.
- M. Castagna, C. Shayakul, D. Trotti, V. Sacchi, W. Harvey, M. Hediger
- Biology, Medicine
- Proceedings of the National Academy of Sciences…
- 28 April 1998
Active solute uptake in bacteria, fungi, plants, and animals is known to be mediated by cotransporters that are driven by Na+ or H+ gradients. The present work extends the Na+ and H+ dogma by… Expand
Molecular characteristics of mammalian and insect amino acid transporters: implications for amino acid homeostasis.
- M. Castagna, C. Shayakul, D. Trotti, V. Sacchi, W. Harvey, M. Hediger
- Biology, Medicine
- The Journal of experimental biology
- 1997
In mammalian cells, the uptake of amino acids is mediated by specialized, energy-dependent and passive transporters with overlapping substrate specificities. Most energy-dependent transporters are… Expand
Segmental localization of urea transporter mRNAs in rat kidney.
- C. Shayakul, M. Knepper, C. Smith, S. Digiovanni, M. Hediger
- Biology, Medicine
- The American journal of physiology
- 1 May 1997
Renal epithelia express at least two distinct urea transporter mRNAs, termed UT1 and UT2, that are derived from a single UT gene by alternative splicing. Previous immunolocalization studies using a… Expand
Autosomal Dominant Distal Renal Tubular Acidosis Is Associated in Three Families with Heterozygosity for the R589H Mutation in the AE1 (Band 3) Cl−/HCO3 −Exchanger*

- Biology, Medicine
- The Journal of Biological Chemistry
- 13 March 1998
Distal renal tubular acidosis (dRTA) is characterized by defective urinary acidification by the distal nephron. Cl−/HCO3 − exchange mediated by the AE1 anion exchanger in the basolateral membrane of… Expand
Molecular characterization of a novel urea transporter from kidney inner medullary collecting ducts.
- C. Shayakul, H. Tsukaguchi, U. Berger, M. Hediger
- Biology, Medicine
- American journal of physiology. Renal physiology
- 1 March 2001
In the terminal part of the kidney collecting duct, rapid urea reabsorption is essential to maintaining medullary hypertonicity, allowing maximal urinary concentration to occur. This process is… Expand
