应用
DNase II from Sigma has been used to treat transformed cells during the purification of β-lactamase. It has also been used for the preparation of adenoma tissue in a study that investigated the effect of somatoprim on growth hormone secretion in human adenoma cell cultures (hSA).
Deoxyribonuclease II from porcine spleen has been used in an immunohistological study of the immune system cells in paraffin-embedded tissues. Deoxyribonuclease II from porcine spleen has also been used in a study to investigate its reassociation with the lysosomal membrane.
生化/生理作用
The enzyme is a lysosomal acid hydrolase that hydrolyzes DNA to 3′-phosphoryl oligonucleotides in the absence of metal ions, under acidic conditions. It is a non-covalently linked α·β heterodimer of approximately 45,000 Da molecular mass.

13C-NMR spectroscopy was used to estimate the p K a values for the Tyr(150) (Y150) residue in wild-type and mutant class C beta-lactamases. The tyrosine residues of the wild-type and mutant lactamases were replaced with (13)C-labelled L-tyrosine ([ phenol -4-(13)C]tyrosine)

Somatostatin analogues (SSA) reduce autonomous GH secretion by activating somatostatin receptors (sst) 2 and 5 in 50-60% of acromegalic patients. However, by inhibiting insulin secretion these SSA reduce glucose tolerance. DG3173 is a novel SSA with additional binding to sst4

Our studies in HUVECs show that ox-LDL induced autophagy and damaged mtDNA leading to TLR9 expression. LOX-1 antibody or the ROS inhibitor apocynin attenuated ox-LDL-mediated autophagy, mtDNA damage and TLR9 expression, suggesting that these events are LOX-1 and ROS-dependent phenomena.

Porcine spleen DNase II (EC 3.1.22.1), one of the best-characterized DNases II, is subcellularly located in lysosomes because the enzyme is co-sedimented with two of the lysosomal marker enzymes, cathepsin D and acid phosphatase. The physicochemical properties, including the subunit

Dying cells release genomic DNA into the surroundings where the DNA is first degraded to oligodeoxynucleotides, then to nucleotides, nucleosides and so on. Given that the unmethylated CpG dinucleotide (CpG motif), which is characteristic of bacterial DNA, is also contained
