Biochem/physiol Actions

The GAL4 protein of yeast activates the transcription of several genes involved in galactose metabolism. This event requires that GAL4 bind to upstream activation sites with the consensus sequence 5`-CGGN5(T/A)N5CCG-3` . A fragment of the GAL4 protein, comprising amino acids 1-147, binds DNA but fails to activate transcription. The adenovirus E1A protein stimulates transcription of a wide variety of viral and cellular genes. In addition to its trans-activating functions, E1A is also able to modulate progression through the cell cycle, to immortalize primary cells in culture and to induce cellular transformation. The E1A protein binds to the TATA-binding protein, TBP, TAFII55 and TAFII110. Its activating domain has been shown to interact with E2F, ATF-2 and YY1.
