However, it is known that the channel is modulated by the P2Y2 receptor which is activated by ATP. The resulting abnormal channel breaks down shortly after it is made, so it never reaches the cell membrane to transport chloride ions. Two transmembrane domains (TMD1 and TMD2), two cytoplasmic nucleotide-binding domains (NBD1 and NBD2) and a regulatory (R) domain make up the CFTR protein.

PMC The cystic fibrosis transmembrane Around the time that the potentiator ivacaftor came to market, its mechanism was being worked out - it binds directly to the phosphorylated CFTR protein at an allosteric site in a way that increases the chances that its chloride "gate" region is open and functional. The CFTR protein is a chloride channel in the cell membrane. The potentiators cause the channels to show increased function, and the correctors increase the number of CFTR proteins that make it to the cell membrane at all. The Hsp70 co-chaperone CHIP has recently gained attention as a regulator of protein turnover. The CFTR protein also regulates the function of other channels, such as those that transport positively charged particles called sodium ions across cell membranes. Federal government websites often end in .gov or .mil. Hes worked for several major pharmaceutical companies since 1989 on drug discovery projects against schizophrenia, Alzheimers, diabetes, osteoporosis and other diseases.
