1ic8 Summary



The structure was published by Chi, Y-.I., Frantz, J.D., Oh, B-.C., Hansen, L., Dhe-Paganon, S., and Shoelson, S.E., in 2002 in a paper entitled "Diabetes mutations delineate an atypical POU domains in HNF1-Alpha" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2001.

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

This PDB entry contains a complex of 3 biomacromolecules, namely 5'-D(*CP*TP*TP*GP*GP*TP*TP*AP*AP*TP*AP*AP*TP*TP*CP*AP*CP*CP*AP*GP*A)-3', 5'-D(*TP*CP*TP*GP*GP*TP*GP*AP*AP*TP*TP*AP*TP*TP*AP*AP*CP*CP*AP*AP*G)-3', and HEPATOCYTE NUCLEAR FACTOR 1-ALPHA.

The molecule most likely forms heterotetramers.
