  DNase footprinting assay
DNase, or deoxyribonuclease, is a class of enzymes which digest DNA.
The most common is the restriction enzyme DNase I, an endonuclease, which digests nucleic acids starting in the middle of the strand (as opposed to an exonuclease which must start at an end).
DNase Footprinting assay is a technique used in molecular biology by which it is possible to determine the location of a protein binding site on cellular DNA.

 DNase footprinting assay - Wikipedia, the free encyclopedia
A DNase footprinting assay [1]is a technique from molecular biology that detects DNA-protein interaction using the fact that a protein bound to DNA will often protect that DNA from enzymatic cleavage.
The method uses an enzyme, deoxyribonucleases (DNases, for short) to cut the DNA, followed by gel electrophoresis to detect the resulting cleavage pattern.

 DNA Footprinting
DNA Footprinting was developed in 1977 and is an analytical procedure in molecular biology for identifying the specific sequence of DNA (the binding site) that binds to a particular protein.
DNA Footprinting can provide information that is, conceptually, much like fingerprinting in the sense that it can be used to identify a unique individual.
DNA Footprinting can extract a banding pattern, or electropherogram, much like a bar code, that can identify a species or individual (some genes will be vary at the species level and others at the individual level).

 Assay - Wikipedia, the free encyclopedia
An assay is a procedure where the concentration of a component part of a mixture is determined.
There are numerous applications of an assay, such as an antigen capture assay, bioassay, competitive protein binding assay, four-point assay, immunoassay, microbiological assay, stem cell assay, and many others.
Assays are regularly utilized in scientific research laboratories.

A DNase footprinting assay is a technique from molecular biology that detects DNA-protein interaction using the fact that a protein bound to DNA will often protect that DNA from enzymatic cleavage.
To examine DNA-protein interactions, the cleavage pattern of isolated DNA is compared with the cleavage pattern of DNA in the presence of the putative binding protein.

Hexose uptake assays and immunoblotting experiments revealed that the breast carcinoma cell lines MCF-7 and MDA-468 express the glucose transporters GLUT1 and GLUT2, isoforms expressed in both normal and neoplastic breast tissue.
Moreover, cotransfection and DNA binding assays demonstrated that increased FoxA2 levels caused a decrease in HNF-6 transcriptional activation of the glucose transporter 2 (Glut-2) promoter by interfering with the binding of HNF-6 to its target DNA sequence.
The GLUT2 and IRS1 amino acid polymorphisms did not show a simple pattern of co-inheritance with NIDDM in the families of these subjects suggesting that neither polymorphism is sufficient to cause NIDDM but may increase diabetes-susceptibility through their interaction with other loci and environmental factors.
