Folding into tertiary structure and
embedding in cell membrane
TMD1 and TMD2 are
transmembrane domains,
each consisting of 6 segments
(1-6 and 7-12, respectively).
ICLS (intracellular loops) and
ECLS (extracellular loops)
connect segments of
transmembrane domains and
contribute to proper function
of the CFTR channel.

Inside cell
NBD1 and NBD2 are nucleotide
binding domains, localized on the
cytoplasmic side of the cell membrane.
ATP hydrolysis of the NBD domains is
required for the CFTR to change
conformation and function as an ion channel.
R represents the regulatory
domain. Phosphorylation
of the R-domain is required
for the CFTR to change
conformation and function
as an ion channel.
