title: Sequences closely related to an immunoglobulin gene promoter/enhancer element occur also upstream of other eukaryotic and of prokaryotic genes.
abstract: Decanucleotide sequences closely related to the TNATTTGCAT element which occurs upstream of the immunoglobulin genes and in the immunoglobulin gene enhancer were found also upstream of other eukaryotic and of prokaryotic genes. The possibility of evolutionary and functional relationships between the various transcriptional systems is discussed.
