This gene encodes a member of the calcium-activated chloride channel regulator (CLCR) family of proteins. Members of this family regulate the transport of chloride across the plasma membrane. The encoded protein is autoproteolytically processed to generate N- and C- terminal fragments. Expression of this gene is upregulated by the tumor suppressor protein p53 in response to DNA damage. In breast cancer, expression of this gene is downregulated and the encoded protein may inhibit migration and invasion while promoting mesenchymal-to-epithelial transition in cancer cell lines.

CLCA2 (Chloride Channel Accessory 2) is a Protein Coding gene. Diseases associated with CLCA2 include Familial Adenomatous Polyposis 2 and Breast Cancer. Among its related pathways are Activation of cAMP-Dependent PKA and Neuropathic Pain-Signaling in Dorsal Horn Neurons. Gene Ontology (GO) annotations related to this gene include metallopeptidase activity and intracellular calcium activated chloride channel activity. An important paralog of this gene is CLCA1.
Chloride channels are a family of anion-selective channels involved in a diverse range of biological processes including the regulation of the excitability of neurons, skeletal, cardiac and smooth muscle, cell volume regulation, transepithelial salt transport, the acidification of intra- and extracellular compartments.
