Summary
The SLC13 gene family includes five proteins that transport sulfate or carboxylates, crucial for cellular functions. This review details their molecular mechanisms, physiological roles, and structures.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics
Background:
- The SLC13 gene family comprises five related proteins found across diverse organisms.
- These proteins function as sodium-coupled cotransporters, divided into Na(+)-sulfate (NaS) and Na(+)-carboxylate (NaC) groups.
- Members include SLC13A1 (NaS1), SLC13A2 (NaC1), SLC13A3 (NaC3), SLC13A4 (NaS2), and SLC13A5 (NaC2).
Purpose of the Study:
- To review the molecular and cellular mechanisms of the SLC13 gene family.
- To elucidate the biochemical, physiological, and structural properties of SLC13 transporters.
- To provide a comprehensive overview of Na(+)-sulfate and Na(+)-carboxylate cotransporter functions.
Main Methods:
- Literature review of studies on SLC13 gene family members.
- Analysis of protein structure, function, and expression patterns.
- Examination of transport mechanisms and substrate specificities.
Main Results:
- SLC13 proteins are plasma membrane transporters with 8-13 transmembrane domains.
- They function as electrogenic Na(+)-coupled symporters with a 3:1 Na(+):anion coupling ratio.
- NaS cotransporters prefer divalent anions like tetra-oxyanions, while NaC cotransporters transport Krebs cycle intermediates.
Conclusions:
- The SLC13 gene family plays vital roles in cellular transport of essential anions.
- Understanding these transporters is key to comprehending various physiological processes.
- Further research into SLC13 mechanisms can reveal therapeutic targets.

01:31Membrane Transporters
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...

01:32Secondary Active Transport
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...

01:14Active Transport
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...

01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
