  • Domain conservation: Help

    The domain N-ter of CF Transmembrane conductance Regulator has been shown to interact with:


    The residue p.Pro41 belongs to the domain N-ter.

    1
    68


    N-ter: N-terminal region is a cytosolic region, also called the "lasso motif" because of its shape.
    The first 40 residues are partially inserted into the membrane, while the end form the "lasso" helix (Zhang et al., 2016).

    The wild-type residue P41 belongs to the N-ter domain and is conserved at 50.41% among the N-ter homologs (62 / 123 N-ter homologs)
    The variant P41R has been found among the N-ter homologs with a non significant frequency: 0.81% (1 / 123 N-ter 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.
