The main function of this domain is the inhibition of DFF40 by binding to its C-terminal catalytic domain through ionic interactions, thereby inhibiting the fragmentation of DNA in the apoptotic process. In addition to blocking the DNase activity of DFF40, the C-terminal region of DFF45 is also important for the DFF40-specific folding chaperone activity, as demonstrated by the ability of DFF45 to refold DFF40 [1].
