Previous GeneCards Identifiers for CLCA2 Gene
The protein encoded by this gene belongs to the calcium sensitive chloride conductance protein family. To date, all members of this gene family map to the same site on chromosome 1p31-p22 and share high degrees of homology in size, sequence and predicted structure, but differ significantly in their tissue distributions. Since this protein is expressed predominantly in trachea and lung, it is suggested to play a role in the complex pathogenesis of cystic fibrosis. It may also serve as adhesion molecule for lung metastatic cancer cells, mediating vascular arrest and colonization, and furthermore, it has been implicated to act as a tumor suppressor gene for breast cancer.

GeneCards Summary for CLCA2 Gene
CLCA2 (Chloride Channel Accessory 2) is a Protein Coding gene. Diseases associated with CLCA2 include cystic fibrosis and breast cancer. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Hepatic ABC Transporters. GO annotations related to this gene include metallopeptidase activity and intracellular calcium activated chloride channel activity. An important paralog of this gene is CLCA1.
UniProtKB/Swiss-Prot for CLCA2 Gene
Plays a role in modulating chloride current across the plasma membrane in a calcium-dependent manner, and cell adhesion. Involved in basal cell adhesion and/or stratification of squamous epithelia. May act as a tumor suppressor in breast and colorectal cancer. Plays a key role for cell adhesion in the beginning stages of lung metastasis via the binding to ITGB4.
Chloride channels are a family of anion-selective channels involved in the regulation of the excitability of neurons, skeletal, cardiac and smooth muscle, cell volume regulation, transepithelial salt transport and the acidification of intra- and extracellular compartments.
