Epithelial Cell Chloride Channel (ClC)

Target
ClC
Molecular classification
Ion channel, Transmembrane protein, Ligand-gated ion channel, Voltage-gated ion channel, ATP-binding cassette transporter
01

Overview

Epithelial cell chloride channels are integral membrane proteins facilitating chloride ion transport across epithelial cell membranes. They regulate transepithelial salt and water movement, cell volume, membrane potential, and signal transduction. Major types include CFTR, voltage-gated ClCs, and calcium-activated ClCs. Dysfunction results in diseases like cystic fibrosis and myotonia.
