Function

Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium.

Biological Context

Subcellular Location: Membrane (Multi-pass membrane protein); Basolateral cell membrane
Tissue Specificity: Widely expressed, with highest levels in adult and fetal kidney (at protein level). In the kidney, expressed in the proximal and distal convoluted tubules, but not in glomeruli nor collecting ducts
Disease Association: Hypokalemic tubulopathy and deafness (HKTD) : An autosomal recessive disease characterized by renal tubulopathy with hypokalemia, salt wasting, disturbed acid-base homeostasis, and sensorineural deafness. [The disease is caused by variants affecting the gene represented in this entry]

Function

Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. KCNJ16 may be involved in the regulation of fluid and pH balance. In the kidney, together with KCNJ10, mediates basolateral K(+) recycling in distal tubules; this process is critical for Na(+) reabsorption at the tubules (PubMed:24561201)

Subunit

It forms heteromeric channels with Kir4.1/KCNJ10; this interaction is required for KCNJ16 localization to the basolateral membrane in kidney cells. As a heteromer with KCNJ10, may interact with MAGI1; this interaction may facilitate KCNJ10/KCNJ16 potassium channel expression at the basolateral membrane in kidney cells (PubMed:24561201). May form heteromers with Kir2.1/KCNJ2 (Probable). Can form heteromeric channels with Kir4.2/KCNJ15 (By similarity)
