CFTR is a 168 kDa member of the ATP-binding cassette (ABC) transporter family. Unlike typical ABC transporters that function as pumps, CFTR is an ion channel. It contains two membrane-spanning domains (MSD1, MSD2), two nucleotide-binding domains (NBD1, NBD2) with Walker A and B motifs, and a regulatory (R) domain. Channel opening requires both ATP binding to NBDs and phosphorylation of the R domain by protein kinase A (PKA).
Although primarily studied in epithelial cells, CFTR is also expressed in the brain, particularly in astrocytes and some neurons. Brain CFTR may regulate:
CFTR expression in brain may be upregulated under inflammatory conditions.
The study of Cftr Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
