Target type: molecularfunction
Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: galactose(out) + Na+(out) = glucose(in) + Na+(in). [TC:2.A.21.3.-]
Galactose:sodium symporter activity is a membrane transport process that simultaneously moves galactose and sodium ions across the cell membrane. This process is driven by the electrochemical gradient of sodium ions, which is maintained by the sodium-potassium pump. Galactose:sodium symporters are typically found in the small intestine and kidney, where they play a crucial role in the absorption of galactose from the diet. This activity involves the binding of both galactose and sodium ions to the transporter protein, triggering a conformational change that allows both molecules to move across the membrane. The symporter has a high affinity for both galactose and sodium, ensuring efficient transport even at low concentrations of these molecules. This process is essential for the uptake of galactose, a monosaccharide, and for maintaining sodium homeostasis in the body.'
