Has DNA hydrolytic activity. Is capable of both single- and double-stranded DNA cleavage, producing DNA fragments with 3'-OH ends (By similarity). Can cleave chromatin to nucleosomal units and cleaves nucleosomal and liposome-coated DNA (PubMed:15796714, PubMed:19154352, PubMed:12095301). Acts in internucleosomal DNA fragmentation (INDF) during apoptosis and necrosis. The role in apoptosis includes myogenic and neuronal differentiation, and BCR-mediated clonal deletion of self-reactive B cells (PubMed:12050166, PubMed:15167901, PubMed:17218958, PubMed:24312463). Is active on chromatin in apoptotic cell-derived membrane-coated microparticles and thus suppresses anti-DNA autoimmunity (PubMed:15796714, PubMed:27293190).
Repeated freezing and thawing is not recommended. Store working aliquots at 4˚C for up to one week.
