In molecular biology, the Bcl-x interacting domain is a
protein domain found in BAM, Bim and
Bcl2-like protein 11. It is a long
alpha helix
The alpha helix (α-helix) is a common motif in the secondary structure of proteins and is a right hand-helix conformation in which every backbone N−H group hydrogen bonds to the backbone C=O group of the amino acid located four residues e ...
, which is required for interaction with
Bcl-x.
