Protein

Cystic fibrosis transmembrane conductance regulator

Gene

CFTR

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Involved 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.1 Publication

Catalytic activityi

ATP + H2O = ADP + phosphate.

Involvement in diseasei

Cystic fibrosis (CF) [MIM:219700]: A common generalized disorder of the exocrine glands which impairs clearance of secretions in a variety of organs. It is characterized by the triad of chronic bronchopulmonary disease (with recurrent respiratory infections), pancreatic insufficiency (which leads to malabsorption and growth retardation) and elevated sweat electrolytes. It is the most common genetic disease in Caucasians, with a prevalence of about 1 in 2'000 live births. Inheritance is autosomal recessive.46 Publications
Note: The disease is caused by mutations affecting the gene represented in this entry.

Post-translational modificationi

Phosphorylated; activates the channel. It is not clear whether PKC phosphorylation itself activates the channel or permits activation by phosphorylation at PKA sites. Phosphorylated by AMPK.6 Publications
Ubiquitinated, leading to its degradation in the lysosome. Deubiquitination by USP10 in early endosomes, enhances its endocytic recycling. Ubiquitinated by RNF185 during ER stress.3 Publications

Isoform 2 (identifier: P13569-2) [UniParc]FASTAAdd to Basket

The sequence of this isoform differs from the canonical sequence as follows:
     404-464: Missing.

Note: Exon skipping favored by a high number of TG repeats and a low number of T repeats at the intron-exon boundary. Causes congenital bilateral absence of the vas deferens (CBAVD).
