Recombinant protein encoding NBF 2 domain of human CFTR.
- Positive control
- General notes
Cystic Fibrosis Transmembrane Regulator (CFTR) is composed of two membrane-spanning domains (MSD), two nucleotide-binding domains (NBD) and one R domain. It is structurally similar to multidrug resistance protein (Mdr1). CFTR is found in the apical membranes of epithelia within the pancreas, intestine, bile duct, sweat gland and male genital ducts. CFTR is a valuable marker of human pancreatic duct cell development and differentiation.

|Flow Cyt||Flow Cyt: Use 1µg for 106 cells.|
- FunctionInvolved in the transport of chloride ions. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the SLC4A7 transporter.
- Tissue specificityFound on the surface of the epithelial cells that line the lungs and other organs.
- Involvement in diseaseDefects in CFTR are the cause of cystic fibrosis (CF) [MIM:219700]; also known as mucoviscidosis. CF is the most common genetic disease in the Caucasian population, with a prevalence of about 1 in 2'000 live births. Inheritance is autosomal recessive. CF is a common generalized disorder of exocrine gland function 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.
Defects in CFTR are the cause of congenital bilateral absence of the vas deferens (CBAVD) [MIM:277180]. CBAVD is an important cause of sterility in men and could represent an incomplete form of cystic fibrosis, as the majority of men suffering from cystic fibrosis lack the vas deferens.
- Sequence similaritiesBelongs to the ABC transporter superfamily. ABCC family. CFTR transporter (TC 3.A.1.202) subfamily.
Contains 2 ABC transmembrane type-1 domains.
Contains 2 ABC transporter domains.
- DomainThe PDZ-binding motif mediates interactions with GOPC and with the SLC4A7, SLC9A3R1/EBP50 complex.
modificationsPhosphorylated; activates the channel. It is not clear whether PKC phosphorylation itself activates the channel or permits activation by phosphorylation at PKA sites.
Ubiquitinated, leading to its degradation in the lysosome. Deubiquitination by USP10 in early endosomes, enhances its endocytic recycling.
- Cellular localizationEarly endosome membrane.

ab4067 staining human tonsil by IHC-P.
Overlay histogram showing A549 cells stained with ab4067 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab4067, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in A549 cells fixed with 80% methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.
