Summary: Enables ATP binding activity; ATP hydrolysis activity; and chloride channel activity. Involved in Kupffer's vesicle development and heart development. Acts upstream of or within several processes, including Spemann organizer formation at the embryonic shield; defense response to other organism; and hemopoiesis. Located in apical plasma membrane. Is expressed in several structures, including Kupffer's vesicle; digestive system; forerunner cell group; head; and pleuroperitoneal region. Used to study cystic fibrosis and diabetes mellitus. Human ortholog(s) of this gene implicated in several diseases, including alcoholic pancreatitis; allergic bronchopulmonary aspergillosis; bronchial disease (multiple); congenital bilateral absence of vas deferens (multiple); and lung disease (multiple). Orthologous to human CFTR (CF transmembrane conductance regulator). [provided by Alliance of Genome Resources, Apr 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
