Inward rectifier potassium channel 16

Gene

Kcnj16

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

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.By similarity

Subunit structurei

Heterodimer with Kir4.1/KCNJ10; this interaction is required for KCNJ16 localization to the basolateral membrane in kidney cells. As a heterodimer with KCNJ10, may interact with MAGI1; this interaction may facilitate KCNJ10/KCNJ16 potassium channel expression at the basolateral membrane in kidney cells. May form heterodimers with Kir2.1/KCNJ2.By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
