  • Domain conservation: Help

    The domain NBD1 of CF Transmembrane conductance Regulator has been shown to interact with:


    The residue p.Pro477 belongs to the domain NBD1.

    423
    649


    NBD1: is the nucleotide binding domain 1, 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.

    The wild-type residue P477 belongs to the NBD1 domain and is conserved at 50.28% among the NBD1 homologs (2002 / 3982 NBD1 homologs)
    The variant P477S has been found among the NBD1 homologs with a non significant frequency: 1.88% (75 / 3982 NBD1 homologs)

    Divergencies show the amino acids which have been selected in the evolution. Residues present in more than 10% of the sequences are highlighted in blue.
