SLC12A1 (Solute Carrier Family 12 Member 1): SLC12A1 is a transporter protein belonging to the solute carrier (SLC) family. It plays a key role in the kidney by facilitating the reabsorption of sodium and chloride ions. This function is essential for maintaining electrolyte balance and regulating blood pressure. In the complex filtration process of the renal system, SLC12A1 ensures precise ion reabsorption to support overall bodily homeostasis.
