• the renal outer medullary potassium (ROMK, Kir1.1) channel is a weak inward rectifying K + channel with a key role in renal K + recycling and secretion (Ho et al., Nature, 1993, 362, 31 ⁇ 38; Shuck et al., The Journal of Biological Chemistry, 1994, 269(39), 24261 ⁇ 24270; Lee and Hebert, American Journal of Physiology ⁇ Renal
• ROMK channel activity provides the K + gradient necessary for Na and Cl reabsorption by the Na + ⁇ K + ⁇ 2Cl ⁇ (NKCC2)
• ROMK channels form the major secretory pathway for K + and as a result, play an important role in K + homeostasis under physiological conditions (Welling and Ho, American Journal of Physiology ⁇ Renal Physiology, 2009, 297(4): F849 ⁇ F863).
• ROMK inhibition may offer a novel mechanism of blood pressure regulation and diuresis in patients suffering from hypertension, congestive heart failure or any other edematous disease conditions.
• NKCC2 transporter The activity of NKCC2 transporter is tightly coupled with ROMK activity in the TAL region and homozygous loss of function mutations in ROMK in humans result in a disease phenotype (renal salt wasting, increased aldosterone levels, metabolic alkalosis, reduction in blood pressure) very similar to that of NKCC2 homozygous mutations but with a milder hypokalemia (Simon et al., Nature Genetics, 1996, 14: 152 ⁇ 156).
