UniProt Annotation
Function Chloride/bicarbonate exchanger. Mediates the efficient absorption of chloride ions in the colon, participating in fluid homeostasis. Plays a role in the chloride and bicarbonate homeostasis during sperm epididymal maturation and capacitation.
Subcellular Localization Apical cell membrane {ECO:0000269PubMed:22159084}; Multi-pass membrane protein {ECO:0000269PubMed:22159084}. Membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Note=Localized in sperm membranes. Midpiece of sperm tail. Colocalizes with CFTR at the midpiece of sperm tail (By similarity). {ECO:0000250}.
Disease Associations Diarrhea 1, secretory chloride, congenital (DIAR1) [MIM:214700]: A disease characterized by voluminous watery stools containing an excess of chloride. The children with this disease are often premature. {ECO:0000269PubMed:11524734, ECO:0000269PubMed:19861545, ECO:0000269PubMed:21150650, ECO:0000269PubMed:21394828, ECO:0000269PubMed:8896562, ECO:0000269PubMed:9554749, ECO:0000269PubMed:9718329}. Note=The disease is caused by mutations affecting the gene represented in this entry.
