ROMK

ROMK is an acronym for the Renal Outer Medullary Potassium channel. This is an ATP-dependent potassium channel (Kir1.1) that transports potassium out of cells.

It plays an important role in potassium recycling in the thick ascending limb (TAL) and potassium secretion in the cortical collecting duct (CCD) of the nephron.
