Physiological Functions
KCNT1 is proposed to assist apical absorption of Na+ and Cl- in transport epithelium, by providing a basolateral hyperpolarizing potential, linked to increases in intracellular Na+ and Cl-.
Species:  Mouse
Tissue:  Kidney (medullary and cortical thick ascending limbs of Henle’s loop)
References:  34
KCNT1 channels are proposed to mediate a fast Na+-dependent component of after-hyperpolarizations in MNTB neurons. The decrease in membrane time constant produced by activation of these channels increases the ability of these neurons to follow high frequency stimuli with temporal precision.

Clinically-Relevant Mutations and Pathophysiology Comments
Additional mutations and information on alterations in KCNT1 function produced by these mutations have been reported [25].
General Comments
KCNT1 and KCNT2 likely encode native KNa channels [1,14,22,42]. Native KNa channels were first recorded from guinea pig cardiac myocytes [23], then later found widely in neurons in the vertebrate central nervous system [15-16,18,26,31,35,40] and dorsal root ganglia [7]. KNa channels have been proposed to protect against hypoxic insult [23], but this and other possible functions remain to be clearly established. Interestingly, C. elegans slo-2 loss-of-function mutants are hypersensitive to hypoxic death [42]. Human mutations in KNa1.1 (KNCT1) give rise to a least three different types of early onset epileptic encephalopathy, each of which has devastating effects on intellectual function [24]. All of the human channel mutations that have been investigated thus far have been found to be associated with several-fold increases in KNa current [2,25,29-30]. The increases in current appear to be caused in major part by enhanced cooperative interactions between individual channels in a cluster [25]. The structure of KNa1.1 channels in the closed state has been resolved by cryo-electron microscopy [19].
