CC -!- FUNCTION: Epithelial ion channel that plays an important role in the
CC regulation of epithelial ion and water transport and fluid homeostasis.
CC Mediates the transport of chloride ions across the cell membrane (By
CC similarity). Channel activity is coupled to ATP hydrolysis. The ion
CC channel is also permeable to HCO(3)(-); selectivity depends on the
CC extracellular chloride concentration. Exerts its function also by
CC modulating the activity of other ion channels and transporters.
CC Contributes to the regulation of the pH and the ion content of the
CC epithelial fluid layer. Modulates the activity of the epithelial sodium
CC channel (ENaC) complex, in part by regulating the cell surface
CC expression of the ENaC complex. May regulate bicarbonate secretion and
CC salvage in epithelial cells by regulating the transporter SLC4A7. Can
CC inhibit the chloride channel activity of ANO1 (By similarity). Plays a
CC role in the chloride and bicarbonate homeostasis during sperm
CC epididymal maturation and capacitation (By similarity).
CC {ECO:0000250|UniProtKB:P13569, ECO:0000250|UniProtKB:P26361}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + closed Cl(-) channel = ADP + phosphate + open
CC Cl(-) channel.; EC=5.6.1.6; Evidence={ECO:0000250|UniProtKB:P13569};
CC -!- SUBUNIT: Monomer; does not require oligomerization for channel
CC activity. May form oligomers in the membrane (By similarity). Interacts
CC with SLC26A3, SLC26A6 and SLC9A3R1 (By similarity). Interacts with
CC SHANK2 (By similarity). Interacts with MYO6 (By similarity). Interacts
CC (via C-terminus) with GOPC (via PDZ domain); this promotes CFTR
CC internalization and thereby decreases channel activity. Interacts with
CC SLC4A7 through SLC9A3R1. Found in a complex with MYO5B and RAB11A.
CC Interacts with ANO1. Interacts with SLC26A8 (By similarity). Interacts
CC with AHCYL1; the interaction increases CFTR activity (By similarity).
CC Interacts with CSE1L (By similarity). The core-glycosylated form
CC interacts with GORASP2 (via PDZ GRASP-type 1 domain) in respone to ER
CC stress (By similarity). Interacts with MARCHF2; the interaction leads
CC to CFTR ubiqtuitination and degradation (By similarity).
CC {ECO:0000250|UniProtKB:P13569, ECO:0000250|UniProtKB:P26361,
CC ECO:0000250|UniProtKB:P34158}.
CC -!- SUBCELLULAR LOCATION: Apical cell membrane
CC {ECO:0000250|UniProtKB:P26361}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P13569}. Early endosome membrane

CC {ECO:0000250|UniProtKB:P26361}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P13569}. Recycling endosome membrane
CC {ECO:0000250|UniProtKB:P13569}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P13569}. Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P13569}; Multi-pass membrane protein
CC {ECO:0000250|UniProtKB:P13569}. Nucleus {ECO:0000250|UniProtKB:P34158}.
CC Note=The channel is internalized from the cell surface into an
CC endosomal recycling compartment, from where it is recycled to the cell
CC membrane. In the oviduct and bronchus, detected on the apical side of
CC epithelial cells, but not associated with cilia. In Sertoli cells, a
CC processed product is detected in the nucleus. ER stress induces
CC GORASP2-mediated unconventional (ER/Golgi-independent) trafficking of
CC core-glycosylated CFTR to cell membrane. {ECO:0000250|UniProtKB:P13569,
CC ECO:0000250|UniProtKB:P34158}.
CC -!- DOMAIN: Binds and hydrolyzes ATP via the two cytoplasmic ABC
CC transporter nucleotide-binding domains. The two ATP-binding domains
CC interact with each other, forming a head-to-tail dimer. Normal ATPase
CC activity requires interaction between the two domains. The first ABC
CC transporter nucleotide-binding domain has no ATPase activity by itself.
CC {ECO:0000250|UniProtKB:P13569, ECO:0000250|UniProtKB:P26361}.
CC -!- DOMAIN: The PDZ-binding motif mediates interactions with GOPC and with
CC the SLC4A7, SLC9A3R1/EBP50 complex. {ECO:0000250|UniProtKB:P13569}.
CC -!- DOMAIN: The disordered R region mediates channel activation when it is
CC phosphorylated, but not in the absence of phosphorylation.
CC {ECO:0000250|UniProtKB:P13569}.
CC -!- PTM: N-glycosylated. {ECO:0000250|UniProtKB:P13569}.
CC -!- PTM: Phosphorylated; cAMP treatment promotes phosphorylation and
CC activates the channel. Dephosphorylation decreases the ATPase activity
CC (in vitro). Phosphorylation at PKA sites activates the channel.
CC Phosphorylation at PKC sites enhances the response to phosphorylation
CC by PKA. Phosphorylated by AMPK; this inhibits channel activity.
CC {ECO:0000250|UniProtKB:P13569}.
CC -!- PTM: Ubiquitinated, leading to its degradation in the lysosome.
CC Deubiquitination by USP10 in early endosomes enhances its endocytic
CC recycling to the cell membrane. Ubiquitinated by RNF185 during ER
CC stress. Ubiquitinated by MARCHF2 (By similarity).
CC {ECO:0000250|UniProtKB:P13569}.
CC -!- SIMILARITY: Belongs to the ABC transporter superfamily. ABCC family.
CC CFTR transporter (TC 3.A.1.202) subfamily. {ECO:0000305}.
