. "\"Interacting selectively and non-covalently with a sequence of DNA that is in cis with and relatively close to a core promoter for RNA polymerase II.\" [GOC:txnOH]" . . "RNA polymerase II core promoter proximal region sequence-specific DNA binding" . "Note that the phrase \"upstream activating sequence\", or UAS is often used in S. cerevisiae literature to refer to regulatory sequences that occur in the region upstream and proximal to the core promoter. In contrast, in bacteria such as E. coli, the phrase \"upstream activating sequence\", or UAS is a synonym for \"enhancer\"." . . .
