• Immunogen: A synthesized peptide derived from human CFTR around the phosphorylation site of Ser737.
• Conjugation: Unconjugated
• Fragment: Fab fragment
• Post Translational Modifications: N-glycosylated.Phosphorylated; cAMP treatment promotes phosphorylation and activates the channel. Dephosphorylation decreases the ATPase activity (in vitro). Phosphorylation at PKA sites activates the channel. Phosphorylation at PKC sites enhances the response to phosphorylation by PKA. Phosphorylated by AMPK; this inhibits channel activity.Ubiquitinated, leading to its degradation in the lysosome. Deubiquitination by USP10 in early endosomes enhances its endocytic recycling to the cell membrane. Ubiquitinated by RNF185 during ER stress.
• Subunit Structure: Monomer; does not require oligomerization for channel activity. May form oligomers in the membrane. Interacts with SLC26A3, SLC26A6 and SHANK2 (By similarity). Interacts with SLC9A3R1 and MYO6. Interacts (via C-terminus) with GOPC (via PDZ domain); this promotes CFTR internalization and thereby decreases channel activity. Interacts with SLC4A7 through SLC9A3R1. Found in a complex with MYO5B and RAB11A. Interacts with ANO1. Interacts with SLC26A8. Interacts with AHCYL1; the interaction increases CFTR activity (By similarity). Interacts with CSE1L. The core-glycosylated form interacts with GORASP2 (via PDZ GRASP-type 1 domain) in respone to ER stress.
• Similarity: Binds and hydrolyzes ATP via the two cytoplasmic ABC transporter nucleotide-binding domains (PubMed:15284228). The two ATP-binding domains interact with each other, forming a head-to-tail dimer (PubMed:17036051). Normal ATPase activity requires interaction between the two domains (PubMed:15284228). The first ABC transporter nucleotide-binding domain has no ATPase activity by itself (By similarity).The PDZ-binding motif mediates interactions with GOPC and with the SLC4A7, SLC9A3R1/EBP50 complex.The R region is intrinsically disordered (PubMed:10792060, PubMed:17660831). It mediates channel activation when it is phosphorylated, but not in the absence of phosphorylation (PubMed:10792060).Belongs to the ABC transporter superfamily. ABCC family. CFTR transporter (TC 3.A.1.202) subfamily.
• Subcellular Location: Apical cell membrane>Multi-pass membrane protein. Early endosome membrane>Multi-pass membrane protein. Cell membrane>Multi-pass membrane protein. Recycling endosome membrane>Multi-pass membrane protein. Endoplasmic reticulum membrane>Multi-pass membrane protein. Nucleus.; Note: The channel is internalized from the cell surface into an endosomal recycling compartment, from where it is recycled to the cell membrane (PubMed:17462998, PubMed:19398555, PubMed:20008117). In the oviduct and bronchus, detected on the apical side of epithelial cells, but not associated with cilia (PubMed:22207244). In Sertoli cells, a processed product is detected in the nucleus (By similarity). ER stress induces GORASP2-mediated unconventional (ER/Golgi-independent) trafficking of core-glycosylated CFTR to cell membrane (PubMed:21884936).
• Preparation and Storage: Store at -20 degree C. Stable for 12 months from date of receipt.

Western Blot (WB)

(Western blot analysis of CFTR (Phospho-Ser737) using COLO205 whole cell lysates.-/+ means absence or presence of N peptide（non-phospho peptide) and P peptide(phospho peptide).)

Immunohistochemistry (IHC)

(Staining Rat spleen tissue sections by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was then blocked and incubated with the antibody for 1.5 hours at 22 degree C. An HRP conjugated goat anti-rabbit antibody was used as the secondary antibody.)

Epithelial ion channel that plays an important role in the regulation of epithelial ion and water transport and fluid homeostasis. Mediates the transport of chloride ions across the cell membrane. Channel activity is coupled to ATP hydrolysis. The ion channel is also permeable to HCO (3-); selectivity depends on the extracellular chloride concentration. Exerts its function also by modulating the activity of other ion channels and transporters. Plays an important role in airway fluid homeostasis. Contributes to the regulation of the pHand the ion content of the airway surface fluid layer and thereby plays an important role in defense against pathogens. Modulates the activity of the epithelial sodium channel (ENaC) complex, in part by regulating the cell surface expression of the ENaC complex. Inhibits the activity of the ENaC channel containing subunits SCNN1A, SCNN1B and SCNN1G. Inhibits the activity of the ENaC channel containing subunits SCNN1D, SCNN1B and SCNN1G, but not of the ENaC channel containing subunits SCNN1A, SCNN1B and SCNN1G. May regulate bicarbonate secretion and salvage in epithelial cells by regulating the transporter SLC4A7. Can inhibit the chloride channel activity of ANO1. Plays a role in the chloride and bicarbonate homeostasis during sperm epididymal maturation and capacitation.

NCBI Description

This 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. [provided by RefSeq, Jul 2008]
