Chloride is a critical component of all living cells.
It is also the single most dominant diffusible anion inside of most cells-the others are mostly impermeable organic anions.
The cation chloride cotransporters (CCC) protein family is involved in the electroneutral movement of ions across the cell membrane.
It includes the thiazide-sensitive Na+Cl- cotransporters (NCC or TSC), the loop diuretics-sensitive Na+K+Cl- (NKCC) cotransporters (NKCC1/CCC1/BSC2 and NKCC2/CCC2/BSC1), and the K+Cl- cotransporters (KCC1-4).
These co-transporters share a common predicted membrane topology, with 12 TM domains (~500 aa), and long hydrophilic, intracellular N-and C-termini containing regulatory phosphorylation sites.
NKCC transport Na, K, and Cl ions into and out of a wide variety of epithelial and non-epithelial cells.
The transport process is characterized by electroneutrality (almost always with stoichiometry of 1Na:1K:2Cl) and inhibition by the loop diuretic bumetanide, benzametanide, and furosemide.
Unlike NKCC1, NKCC2 (human 1099 aa, rat/mouse 1095 aa; calculated mol size of ~121kD; actual size ~150kD; ~45% identity with NKCC1) is most strongly expressed in the kidney (inner and outer stripes of medulla and cortical thick ascending limb), and macula densa.
NKCC2 plays a critical role in transcellular absorption of Na+Cl- by the medullary and cortical TALH, and a secondary role in the paracellular transport of Na-Ca and Mg.
Mutations in the NKCC2 gene result in Bartter's syndrome, an inherited disease characterized by hypokalemic metabolic alkalosis, hypercalciuria, salt wasting, and volume depletion.
