  • Domain conservation: Help

    The domain NBD2 of CF Transmembrane conductance Regulator has been shown to interact with:


    The residue p.His1375 belongs to the domain NBD2.

    1210
    1443


    NBD2: is the nucleotide binding domain 2, also called the ATP-binding cassette (ABC).
    It contains the Walker A (P-loop) and Walker B motifs, the C-motif (also known as the signature sequence), the A-, D-, Q-, and H-loops.
