摘要
In order to study the binding of the Myb-like domain of the human telomeric protein TRF2 (Myb-TRF2) with different structural components of the t-loop model, we report NMR studies of the binding of Myb-TRF2 protein with two repeats human telomeric DNA under three conformations. Our results showed that Myb-TRF2 binds to the duplex and even to the quadruplex and the random coil G-rich strand. The solution structure of Myb-TRF2 reported here looks like Myb-TRF1 suggesting similar DNA binding mode. As a matter of fact, we have shown that its binding to the human telomeric duplex presents great similarities with this of Myb-TRF1.
