Sodium-Potassium-Chloride Symporter (NKCC)

Target
NKCC
Molecular classification
Transporter, Membrane Transport Protein, SLC12 family
01

Overview

The sodium-potassium-chloride symporter (NKCC) is a membrane transport protein that facilitates the coupled movement of sodium (Na⁺), potassium (K⁺), and chloride (Cl⁻) ions across cellular membranes. It plays a critical role in ion homeostasis, cell volume regulation, and neuronal excitability. There are two main isoforms: NKCC1 (ubiquitous) and NKCC2 (kidney-specific). Inhibitors like bumetanide and furosemide are used as diuretics.
