The interaction of TFIIIA with specific RNA-DNA heteroduplexes.
???displayArticle.abstract???
We examine the association of transcription factor TFIIIA with RNA-DNA heteroduplexes containing sequences from the Xenopus borealis 5 S rRNA gene. Under conditions where TFIIIA selectively binds to 5 S rRNA or the internal control region of the 5 S rRNA gene, no specific association of TFIIIA with DNA-RNA heteroduplexes containing either strand of 5 S DNA could be detected. We discuss our results with respect to specific models of TFIIIA recognition of the internal control region and of DNA-RNA hybrids by zinc finger proteins.
