title: Characterization of a promoter region supporting transcription of a novel human beta-galactoside alpha-2,6-sialyltransferase transcript in HepG2 cells.
abstract: In humans, two transcripts encoding beta-galactoside alpha-2,6-sialytransferase (EC 2.4.99.1.) have previously been described. One of the transcripts is widely expressed, whereas the other is restricted to mature B-cells. In this study we demonstrate the existence of a third transcript in the hepatoma cell-line HepG2. The expression of this transcript is controlled by a promoter region which efficiently supports transcription in HepG2 cells, and which harbours putative binding sites for liver-enriched and acute phase inducible transcription factors.
