Protein

Calcium-activated chloride channel regulator 2

Gene

Clca2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at transcript leveli

Functioni

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 ITGB4.2 Publications

Post-translational modificationi

The translation product is autoproteolytically cleaved by the metalloprotease domain in the endoplasmic reticulum into a N-terminal and a C-terminal products that remain physically associated with each other. The cleavage is necessary for calcium-activated chloride channel (CaCC) activation activity.By similarity

Expressioni

Tissue specificityi

Highly expressed in eye, spleen, lung, kidney, uterus, and endothelial cells. Weakly expressed in heart and throughout the gastrointestinal tract. Highly expressed in mammary cell lines. Its expression in immortalized cell line HC11 correlates with slow or arrested growth. Re-expression in mammary tumor cells reduces colony survival.2 Publications

Inductioni

By 30-fold when cells are deprived of growth factors or anchorage in mammary epithelial cell. Down-regulated in metastatic mammary tumor cell lines.1 Publication
