'''Cystic fibrosis transmembrane conductance regulator (CFTR) nucleotide-binding domain one (NBD1) with ATP, I4122 space group'''<br />


==Overview==
==Cystic fibrosis transmembrane conductance regulator (CFTR) nucleotide-binding domain one (NBD1) with ATP, I4122 space group==
Cystic fibrosis transmembrane conductance regulator (CFTR) is an, ATP-binding cassette (ABC) transporter that functions as a chloride, channel. Nucleotide-binding domain 1 (NBD1), one of two ABC domains in, CFTR, also contains sites for the predominant CF-causing mutation and, potentially, for regulatory phosphorylation. We have determined crystal, structures for mouse NBD1 in unliganded, ADP- and ATP-bound states, with, and without phosphorylation. This NBD1 differs from typical ABC domains in, having added regulatory segments, a foreshortened subdomain, interconnection, and an unusual nucleotide conformation. Moreover, isolated NBD1 has undetectable ATPase activity and its structure is, essentially the same independent of ligand state. Phe508, which is, commonly deleted in CF, is exposed at a putative NBD1-transmembrane, interface. Our results are consistent with a CFTR mechanism, whereby, channel gating occurs through ATP binding in an NBD1-NBD2 nucleotide, sandwich that forms upon displacement of NBD1 regulatory segments.
