Deoxyribonuclease-1
dnase1
Functioni
Serum endocuclease secreted into body fluids by a wide variety of exocrine and endocrine organs (PubMed:9395327).
Expressed by non-hematopoietic tissues and preferentially cleaves protein-free DNA (By similarity).
Among other functions, seems to be involved in cell death by apoptosis (By similarity).
Binds specifically to G-actin and blocks actin polymerization. Preferentially attacks double-stranded DNA and produces oligonucleotides with 5'-phospho and 3'-hydroxy termini (PubMed:9395327).
