Proteome Chips: Mismatch Binding         

Description:

Chen (2008) identified the top 20 proteins that preferentially bind to dsDNA containing an abasic site (N) unpaired to a A, called probe 5. Probe 1 is the same 19-mer with a G:C instead of the A-N.

Details:

5'-GGAATTAAAGNGAAGACC-3'
3'- CCTTAATTTCACTTCTGG-5

The ratio of the preferential probe 5 binding ranges from 13.2 fold for Dgt to 1.9 fold for YdcA. YbaZ is ranked second at 8.0 fold.
