CRYSTAL STRUCTURE OF CASPASE-ACTIVATED DNASE (CAD)
Overview
CAD/DFF40 is responsible for the degradation of chromosomal DNA into, nucleosomal fragments and subsequent chromatin condensation during, apoptosis. It exists as an inactive complex with its inhibitor ICAD/DFF45, in proliferating cells but becomes activated upon cleavage of ICAD/DFF45, into three domains by caspases in dying cells. The molecular mechanism, underlying the control and activation of CAD/DFF40 was unknown. Here, the, crystal structure of activated CAD/DFF40 reveals that it is a pair of, molecular scissors with a deep active-site crevice that appears ideal for, distinguishing internucleosomal DNA from nucleosomal DNA. Ensuing studies, show that ICAD/DFF45 sequesters the nonfunctional CAD/DFF40 monomer and is, also able to disassemble the functional CAD/DFF40 dimer. This ... [(full description)]
