synthetic peptide corresponding to amino acids 205-222 of mouse CAD (cell death-inducing DFF-like effector A).

General description

Caspase Activated DNase is a heterodimeric protein composed of ICAD and CAD (in human known as DFF45 and DFF40, respectively) two subunits, which triggers DNA fragmentation during apoptosis.

Physical form

Solution in phosphate buffered saline, containing 0.02% sodium azide.


Anti-CAD antibody was used for western blotting in a study of simultaneous downregulation of uPAR (urokinase-type plasminogen activator receptor] and Cathepsin B induces the up-regulation of pro-apoptotic genes.

Biochem/physiol Actions

In inactive state DFF exists as a cytoplasmic protein. After activated by apoptotic signals DFF45 functions as a chaperone, mediating the correct folding of DFF40, as well as an inhibitor of DFF40. In response to apoptotic signals, DFF45 is cleaved by caspase-3 at two sites; which results releasing of active nuclease, DFF40. Furthermore, DFF40 oligomerize to form a large, functional complex which further breaks down DNA by introducing double-strand breaks. However, DFF40 interact directly with histone H1 which may stimulate its activity.
