Deoxyribonuclease I (usually called DNase I), is an endonuclease coded by the human gene DNASE1.^[1] DNase I is a nuclease that cleaves DNA preferentially at phosphodiester linkages adjacent to a pyrimidine nucleotide, yielding 5'-phosphate-terminated polynucleotides with a free hydroxyl group on position 3', on average producing tetranucleotides. It acts on single-stranded DNA, double-stranded DNA, and chromatin. It has been suggested to be one of the deoxyribonucleases responsible for DNA fragmentation during apoptosis.

DNase I binds to the cytoskeletal protein actin. It binds actin monomers with very high (sub-nanomolar) affinity and actin polymers with lower affinity. The function of this interaction is unclear. However, since actin-bound DNase I is enzymatically inactive, the DNase-actin complex might be a storage form of DNase I that prevents damage of the genetic information.

This gene encodes a member of the DNase family. This protein is stored in the zymogen granules of the nuclear envelope and functions by cleaving DNA in an endonucleolytic manner. At least six autosomal codominant alleles have been characterized, DNASE1*1 through DNASE1*6, and the sequence of DNASE1*2 represented in this record. Mutations in this gene, as well as factor inactivating its enzyme product, have been associated with systemic lupus erythematosus (SLE), an autoimmune disease.^[2][3] A recombinant form of this protein is used to treat one of the symptoms of cystic fibrosis by hydrolyzing the extracellular DNA in sputum and reducing its viscosity.^[4] Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized.^[1]
