Protein Information (annotations from UniProt)

Database IDHIV0000590
UniProt IDP13569
Primary gene name(s)CFTR
Synonym gene name(s)ABCC7
Protein nameCystic fibrosis transmembrane conductance regulator
Protein functionInvolved in the transport of chloride ions. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the SLC4A7 transporter. Can inhibit the chloride channel activity of ANO1. Plays a role in the chloride and bicarbonate homeostasis during sperm epididymal maturation and capacitation. {ECO:0000269|PubMed:22178883}.
Subcellular locationEarly endosome membrane {ECO:0000269|PubMed:19398555};
Multi-pass membrane protein {ECO:0000255}. Cell membrane {ECO:0000269|PubMed:22178883};
Multi-pass membrane protein {ECO:0000255}. Note=In the oviduct and bronchus, detected on the apical side of epithelial cells, but not associated with cilia. {ECO:0000269|PubMed:22207244}.
