Drosophila genome contains near 30 transcription factors containing BTB-domains able to form octamers (TTK group). Spatial structure of two domains of this group - CG6765 and CG32121 was studied using small-angle X-ray scattering (SAXS). SAXS data confirm that these domains are able to form octamers and provide insight into the structure of such octamers.
