cDNA cloning and characterization of mouse DTEF-1 and ETF, members of the TEA/ATTS family of transcription factors.

Members of the TEA/ATTS family of transcription factors have been found in most representative eukaryotic organisms. In vertebrates, the TEA family contains at least four members, which share overlapping DNA-binding specificity and have similar transcriptional activation properties. In this article, we describe the cDNA cloning and characterization of the murine TEA proteins DTEF-1 (mDTEF-1) and ETF. Using in situ hybridization analysis of mouse embryos, we found that mDTEF-1 and ETF transcript distributions substantially overlap. ETF is expressed throughout the embryo except in the myocardium early in development, whereas late in development, it is enriched in lung and neuroectoderm. Mouse DTEF-1 is expressed at a much lower level throughout development and is substantially enriched in ectoderm and skin, as well as in the developing pituitary at midgestation. Northern blot analysis of adult mouse tissue total RNA showed that both ETF and mDTEF-1 are abundant in uterus and lung relative to other tissues. Using gel mobility shift assays and GAL4-fusion protein analysis, we demonstrated that the full coding sequences of ETF and mDTEF-1 encode M-CAT/GT-IIC-binding proteins containing activation domains.[1]
