Summarize current understanding of how associate proteins interact with the ROMK channel to assemble and regulate native renal potassium secretory channels.
Narrative synthesis of molecular and physiological studies assessing ROMK channel function and regulation.
Comparative analysis between cloned ROMK channels and native potassium secretory channels across the thick ascending limb and cortical collecting duct.
Identified functional discrepancies between isolated ROMK channels and native potassium secretory channels, indicating that ROMK alone is insufficient to replicate native channel properties.
Demonstrated that interactions with associate proteins, specifically CFTR and AKAP, are required to restore channel sensitivity to ATP and responsiveness to protein kinase A stimulation.

Implication

CFTR and AKAP interactions are required for native ROMK function; extends molecular models of renal K secretion but leaves open clinical translation.
