PIT-1 MUTANT/DNA COMPLEX

The structure was published by Jacobson, E.M., Li, P., Leon-del-Rio, A., Rosenfeld, M.G., and Aggarwal, A.K., in 1997 in a paper entitled "Structure of Pit-1 POU domain bound to DNA as a dimer: unexpected arrangement and flexibility." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 1997.

The experimental data on which the structure is based was not deposited.

This PDB entry contains a complex of 3 biomacromolecules, namely CONSENSUS DNA 25-MER, DNA (5'-D(*CP*TP*TP*CP*CP*TP*CP*AP*TP*GP*TP*AP*TP*AP*TP*AP*C P*AP*TP*GP*AP*GP* GP*A)-3'), and PROTEIN PIT-1.

The molecule most likely forms heterotetramers.
