NMR Solution Stucture of the Extended PBX Homeodomain Bound to DNA

The structure was published by Sprules, T., Green, N., Featherstone, M., and Gehring, K., in 2003 in a paper entitled "Lock and Key Binding of the HOX YPWM Peptide to the PBX Homeodomain" (abstract).

The structure was determined using NMR spectroscopy and deposited in 2002.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely 5'-D(*GP*CP*GP*CP*AP*TP*GP*AP*TP*TP*GP*CP*CP*C)-3', 5'-D(*GP*GP*GP*CP*AP*AP*TP*CP*AP*TP*GP*CP*GP*C)-3', and homeobox protein PBX1.

The molecule most likely forms heterotrimers.
