Death Domain

Also found in: Acronyms.
A molecular domain present in many apoptosis pathway proteins and others for which there is no known role in apoptosis. Several death domain-containing proteins serve as adaptor molecules, mediating associations between proteins that contain DDs—homotypic DD interactions
