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