The Na-K-Cl Cotransporter of Secretory Epithelia

Haas, Mark, Forbush III, Bliss·2000·Annual Review of Physiology

Abstract

▪ Abstract The Na-K-Cl cotransporters are a class of ion transport proteins that transport Na, K, and Cl ions into and out of cells in an electrically neutral manner, in most cases with a stoichiometry of 1Na:1K:2Cl. To date, two Na-K-Cl cotransporter isoforms have been identified: NKCC1, which is present in a wide variety of secretory epithelia and non-epithelial cells; and NKCC2, which is present exclusively in the kidney, in the epithelial cells of the thick ascending limb of Henle’s loop and of the macula densa. Both NKCC isoforms represent part of a diverse family of cationchloride cotransport proteins that share a common predicted membrane topology; this family also includes Na-Cl cotransporters and multiple K-Cl cotransporter isoforms. In secretory epithelia, the regulation of NKCC1, which is typically present on the basolateral membrane, is tightly coordinated with that of other transporters, including apical Cl channels, to maintain cell volume and integrity during active salt and fluid secretion. Changes in intracellular [Cl] ([Cl]i) appear to be involved in this regulation of NKCC1, which is directly phosphorylated by an unknown protein kinase in response to various secretagogues as well as reductions in [Cl]i and cell volume. This review focuses on structure-function relationships within NKCC1 and on recent developments pertaining to NKCC1 regulation at cellular and molecular levels.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
