Uses
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project
(www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. To view these

General Description
CLCN2 (chloride channel, voltage-sensitive 2) is a member of the voltage gated Cl
- channels and Cl
-/H
+ exchangers called ClC family of proteins. The mammalian family consists of nine members including CLCN2. This protein has a ubiquitous expression pattern. It has a predominant expression in brain, pancreas, kidney and intestine. This protein is localized intracellulary in the basolateral membrane of polarized cells. It exists as aggregates on the cell surface, and some proportion of it localized with lipid rafts. This protein consists of two putative phosphorylation sites in its N-terminal, and seven in its C-terminal.
Biochem/physiol Actions
CLCN2 (chloride channel, voltage-sensitive 2) has a high level of expression in the brain, where it mediates inhibitory γ-aminobutyric acid (GABA) response. It maintains low intracellular Cl- levels, to achieve this. Hyperpolarization of membrane and intracellular anion concentration activate CLCN2, and it is involved in solute transport across epithelial cells. It is expressed in lung epithelia, where it is capable of Cl- transport. It might also be involved in the morphogenesis of lungs. In astrocytes, this protein is involved in the maintenance of extracellular electrolyte homeostasis. Mutation M200fsX231 produces an extremely truncated CLCN2 protein, and might be linked with idiopathic generalized epilepsy. Studies also suggest that this protein might be associated with atherosclerosis and constipation-associated irritable bowel disease. Studies show that the susceptibility to a subset of childhood absence epilepsies maybe linked to CLCN2 gene locus.
