Solution Structure of Steroidogenic Factor 1 DNA Binding Domain Bound to its Target Sequence in the Inhibin alpha-subunit Promoter

The structure was published by Little, T.H., Zhang, Y., Matulis, C.K., et al., Ramachandran, A., Mayo, K.E., and Radhakrishnan, I., in 2006 in a paper entitled "Sequence-specific deoxyribonucleic Acid (DNA) recognition by steroidogenic factor 1: a helix at the carboxy terminus of the DNA binding domain is necessary for complex stability." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2005.

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

This PDB entry contains a complex of 3 biomacromolecules, namely GGCTCAGGGCCACAG, CTGTGGCCCTGAGCC, and Steroidogenic factor 1.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotrimers.
