myo-inositol:sodium symporter activity
Definition
Target type: molecularfunction
Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: myo-inositol(out) + Na+(out) = myo-inositol(in) + Na+(in). [TC:2.A.21.4.-]
Myo-inositol:sodium symporter activity describes the facilitated movement of myo-inositol across the cell membrane, coupled with the movement of sodium ions. This transport process is driven by the electrochemical gradient of sodium ions, which are typically higher in concentration outside the cell. As sodium ions move down their concentration gradient into the cell, they provide the energy to drive the uptake of myo-inositol, which is typically present in lower concentrations inside the cell. This symporter activity is crucial for cellular processes that rely on myo-inositol, including phosphoinositide signaling, osmotic regulation, and the synthesis of inositol phosphates, which serve as second messengers in various signaling pathways. The symporter protein itself is embedded in the cell membrane and exhibits high specificity for both myo-inositol and sodium ions, ensuring that the correct molecules are transported. Its activity can be modulated by factors such as pH, temperature, and the presence of specific inhibitors or activators, providing a mechanism for regulating cellular myo-inositol levels. '
