This gene encodes a member of the calcium sensitive chloride conductance protein family. To date, all members of this gene family map to the same region on chromosome 1p31-p22 and share a high degree of homology in size, sequence, and predicted structure, but differ significantly in their tissue distributions. The encoded protein is expressed as a precursor protein that is processed into two cell-surface-associated subunits, although the site at which the precursor is cleaved has not been precisely determined. The encoded protein may be involved in mediating calcium-activated chloride conductance in the intestine. [provided by RefSeq, Jul 2008]
CLCA1 (Chloride Channel Accessory 1) is a Protein Coding gene. Diseases associated with CLCA1 include Cystic Fibrosis and Pontocerebellar Hypoplasia, Type 9. 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 CLCA4.
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.
