Summary
The Na-sulfate cotransporter (NaS1) is crucial for kidney and gut sulfate balance. Disrupting NaS1 in mice caused significant metabolic and physiological problems, highlighting its importance in sulfate homeostasis.
Area of Science:
- Physiology
- Molecular Biology
- Biochemistry
Background:
- Sulfate is vital for normal physiological functions.
- The kidney is central to maintaining sulfate homeostasis through filtration and reabsorption.
- The Na(+)-sulfate cotransporter 1 (NaS1), encoded by SLC13A1, is key for renal and intestinal sulfate transport.
Purpose of the Study:
- To investigate the role of NaS1 in sulfate homeostasis.
- To understand the physiological consequences of NaS1 disruption.
Main Methods:
- Analysis of NaS1 gene and protein expression.
- Investigation of NaS1 substrate specificity and inhibition.
- Phenotypic analysis of NaS1 knockout mice.
Main Results:
- NaS1 mediates the transport of sodium and sulfate, thiosulfate, and selenate.
- NaS1 expression in the kidney and intestine is regulated by various dietary and hormonal factors.
- NaS1 gene disruption in mice resulted in hyposulfatemia, hypersulfaturia, and widespread metabolic and physiological disturbances.
Conclusions:
- NaS1 is a critical transporter for maintaining sulfate balance in the body.
- Perturbations in sulfate homeostasis due to NaS1 dysfunction contribute to various pathophysiological conditions.

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme "pump" embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

The pharmacogenetics of drug transporters is increasingly recognized as a critical factor influencing interindividual variability in drug absorption, distribution, and elimination. These membrane-bound proteins regulate drugs' movement across cellular barriers by actively pumping them out (efflux) or facilitating their uptake (influx). Among the major transporter families, ATP-binding cassette (ABC) and solute carrier (SLC) transporters play particularly prominent roles. Genetic polymorphisms...

Transporters are essential membrane transport proteins with functions related to cell nutrition, homeostasis, communication, etc. Approximately 7% of all genes in the human genome code for transporters or transporter-related proteins.
Transporters are mainly composed of alpha-helices, built from bundles of ten or more helices traversing the plasma membrane. The solute-binding sites are located midway, where some of the helices are broken or distorted, making space for the binding site through...

Active transport is a critical biological process that allows cells to move solutes against an electrochemical gradient. This process requires direct energy input and is characterized by its selectivity, saturability, and susceptibility to competitive inhibition.
Primary active transporters, like Na+, K+ and -ATPase, directly utilize ATP to move ions across the membrane. These transporters play significant roles in various physiological processes. For instance, Na+, K+ and -ATPase maintain...
