Sequence status	Complete.

Protein existence	Evidence at protein level

General annotation (Comments)

Function	Among other functions, seems to be involved in cell death by apoptosis. Binds specifically to G-actin and blocks actin polymerization By similarity.
Catalytic activity	Endonucleolytic cleavage to 5'-phosphodinucleotide and 5'-phosphooligonucleotide end-products.
Cofactor	Divalent cations. Prefers calcium or magnesium.
Subcellular location	Secreted. Nucleus envelope. Note: Secretory protein, stored in zymogen granules and found in the nuclear envelope.
Tissue specificity	Principally in tissues of the digestive system. Highest levels found in urine, but also relatively abundant in semen and saliva.
Polymorphism	At least 6 alleles of DNASE1 are known: DNASE1*1 to DNASE1*6. The sequence shown is that of DNASE1*2.
Involvement in disease	Systemic lupus erythematosus (SLE) [MIM:152700]: A chronic, relapsing, inflammatory, and often febrile multisystemic disorder of connective tissue, characterized principally by involvement of the skin, joints, kidneys and serosal membranes. It is of unknown etiology, but is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The disease is marked by a wide range of system dysfunctions, an elevated erythrocyte sedimentation rate, and the formation of LE cells in the blood or bone marrow. Note: Disease susceptibility is associated with variations affecting the gene represented in this entry. Ref.10
Pharmaceutical use	Available under the name Pulmozyme (Genentech). Used to reduce the viscosity of cystic fibrosis sputum by hydrolyzing the extracellular DNA released by degenerating leukocytes that accumulate in response to infection.
Sequence similarities	Belongs to the DNase I family.
