Protein

Solute carrier family 12 member 7

Gene

SLC12A7

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Mediates electroneutral potassium-chloride cotransport when activated by cell swelling. May mediate K+ uptake into Deiters' cells in the cochlea and contribute to K+ recycling in the inner ear. Important for the survival of cochlear outer and inner hair cells and the maintenance of the organ of Corti. May be required for basolateral Cl- extrusion in the kidney and contribute to renal acidification (By similarity).By similarity1 Publication

Enzyme regulationi

Activated by N-ethylmaleimide (NEM). Inhibited by furosemide, DIDS and bumetanide. The inhibition is much stronger in the presence of 50 mM K+ in the uptake medium. Inhibited by DIOA. Inhibited by WNK3.1 Publication

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.
