Structure and transforming potential of the human cot oncogene encoding a putative protein kinase.

abstract：:Previous investigations have defined three upstream activation elements--CCAC, A/T, and TATA sequences--necessary for muscle-specific transcription of the myoglobin gene. In the present study, we demonstrate that these three sequences elements, prepared as synthetic oligonucleotide cassettes, function synergistically ...

To investigate the role of TFIIA in TFIID recruitment in vivo, we exploited a class of yeast TATA-binding protein (TBP) mutants that is activation and DNA binding defective. We found that co-overexpr...
