What is the official name of the CLCNKB gene?
The official name of this gene is “chloride channel, voltage-sensitive Kb.”
CLCNKB is the gene's official symbol. The CLCNKB gene is also known by other names, listed below.

What is the normal function of the CLCNKB gene?
The CLCNKB gene belongs to the CLC family of genes, which provide instructions for making chloride channels. These channels, which transport negatively charged chlorine atoms (chloride ions), play a key role in a cell's ability to generate and transmit electrical signals. Some CLC channels regulate the flow of chloride ions across cell membranes, while others transport chloride ions within cells.
The CLCNKB gene provides instructions for making a chloride channel called ClC-Kb. These channels are found predominantly in the kidneys. ClC-Kb is one of several proteins that work together to regulate the movement of ions into and out of kidney cells. The transport of chloride ions by ClC-Kb channels is part of the mechanism by which the kidneys reabsorb salt (sodium chloride or NaCl) from the urine back into the bloodstream. The retention of salt affects the body's fluid levels and helps maintain blood pressure.
ClC-Kb channels are also located in the inner ear, where they play a role in normal hearing.
Does the CLCNKB gene share characteristics with other genes?
The CLCNKB gene belongs to a family of genes called CLCN (chloride channels, voltage-sensitive).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
