As studies aim increasingly to understand key, evolutionarily conserved properties of biological systems, the ability to move transgenesis experiments efficiently between organisms becomes essential. DNA constructions used in transgenesis usually contain four elements, including sequences that facilitate transgene genome integration, a selectable marker and promoter elements driving a coding gene. Linking these four elements in a DNA construction, however, can be a rate-limiting step in the design and creation of transgenic organisms.

CBTF122 is a subunit of the Xenopus CCAAT box transcription factor complex and a member of a family of double-stranded RNA-binding proteins that function in both transcriptional and post-transcriptional control. Here we identify a region of CBTF122 containing the double-stranded RNA-binding domains that is capable of binding either RNA or DNA. We show that these domains bind A-form DNA in preference to B-form DNA and that the -59 to -31 region of the GATA-2 promoter (an in vivo target of CCAAT box transcription factor) adopts a partial A-form structure.
