      Background InformationCFTR (Cystic Fibrosis Transmembrane conductance Regulator) is a 170 kDa chloride (Cl-) channel that regulates salt and water transport across epithelial tissues, where it modulates production of mucus, sweat, saliva, tears, and digestive enzymes. Cystic fibrosis patients have mutations in this protein, resulting in defective in ion transport. Symptoms include reduced transport of sodium chloride (saltier sweat) and digestive and respiratory disorders caused by thicker mucus. CFTR mutations are also associated with congenital bilateral absence of the vas deferens in males.

      Key Applications
      • Immunocytochemistry
      • Immunoprecipitation
      • Western Blotting
      Application NotesImmunoprecipitation:
      This antibody has been shown to immunoprecipitate CFTR from a T84 cell lysate by an independent laboratory.

      This antibody has been reported to immunostain CFTR in T84 cells.
      Biological Information
      ImmunogenSynthetic peptide (RKGYRQRLELSD) corresponding to residues 25-36 of human cystic fibrosis transmembrane conductance regulator (CFTR). The immunizing sequence is identical in monkey and rabbit, has 11/12 identical amino acids in sheep, cow and frog, 10/12 identity in mouse and 9/12 identity in rat. Clone MM13-4.
      ConcentrationPlease refer to the Certificate of Analysis for the lot-specific concentration.
      SpecificityThis antibody recognizes CFTR, Mr 170kDa. Two additional proteins were detected, Mr 52 and 38 kDa, in CFTR-transfected BHK cell lysates.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the ATP-binding cassette (ABC) transporter superfamily. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the MRP subfamily that is involved in multi-drug resistance. The encoded protein functions as a chloride channel and controls the regulation of other transport pathways. Mutations in this gene are associated with the autosomal recessive disorders cystic fibrosis and congenital bilateral aplasia of the vas deferens. Alternatively spliced transcript variants have been described, many of which result from mutations in this gene.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P13569 # Involved in the transport of chloride ions. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the SLC4A7 transporter.
      SIZE: 1480 amino acids; 168142 Da
      SUBUNIT: Interacts with SHANK2 (By similarity). Interacts with SLC9A3R1, MYO6 and GOPC. Interacts with SLC4A7 through SLC9A3R1.
      SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein.
      TISSUE SPECIFICITY: Found on the surface of the epithelial cells that line the lungs and other organs.
      DOMAIN: SwissProt: P13569 The PDZ-binding motif mediates interactions with GOPC and with the SLC4A7, SLC9A3R1/EBP50 complex.
      DISEASE: SwissProt: P13569 # Defects 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 2000 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.
      SIMILARITY: Belongs to the ABC transporter family. CFTR transporter (TC 3.A.1.202) subfamily. & Contains 2 ABC transmembrane type-1 domains. & Contains 2 ABC transporter domains.
