| | POLY(ETHYLENE GLYCOL) BUTYL ETHER Usage And Synthesis |
| Definition | ChEBI: 2-butoxyethanol is a primary alcohol that is ethanol in which one of the methyl hydrogens is replaced by a butoxy group. A high-boiling (171℃) colourless liquid, it is used as a solvent for paints and inks, as well as in some dry cleaning solutions. It has a role as a protic solvent. It is a primary alcohol and a glycol ether. | | Biological Activity | The GAL4 protein of yeast activates the transcription of several genes involved in galactose metabolism. This event requires th at 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. |
