Preliminary crystallographic analysis of mouse Elf3 C-terminal DNA-binding domain in complex with type II TGF-b receptor promoter DNA

Ets proteins are transcription factors that activate or repress the expression of genes that are involved in various biological processes, including cellular proliferation, differentiation, development, transformation and apoptosis. Like other Ets-family members, Elf3 functions as a sequence-specific DNA-binding transcriptional factor. A mouse Elf3 C-terminal fragment (amino-acid residues 269-371) containing the DNA-binding domain has been crystallized in complex with mouse type II TGF-b receptor promoter (TbR-II) DNA. The crystals belonged to space group P212121, with unit-cell parameters a = 42.66, b = 52, c = 99.78 Aa, and diffracted to a resolution of 2.2 Aa.
