Funkcija uredi

Hloridni kanal Kb (CLCNKB) je član porodice CLC naponski-ovisnih hloridnih kanala, koji sadrži najmanje 9 hloridnih kanala sisara.^[7] Vjeruje se da svaki ima 12 transmembranskih domena i unutarćelijske N- i C-krajeve. Mutacije u CLCNKB dovode do autosomno recesivnog tipa III Bartterovog sindroma.^[8]CLCNKA i CLCNKB su usko povezani (94% identičnost sekvence), čvrsto povezani (odvojeni sa 11 kb genomske sekvence) i oba su eksprimirana u bubrezima sisara.^[5]
