title: Drosophila melanogaster U1 and U2 small nuclear RNA genes contain common flanking sequences.
abstract: The flanking sequences of three U2 genes (or pseudogenes) and one U1 gene of Drosophila melanogaster have been determined. Comparison of the sequences reveals a remarkable homology between position -30 and -65 upstream from the structural genes, starting with a TATA box-like sequence. The 3' flanking regions are also conserved in all genes and contain a canonical A-A-T-A-A-A polyadenylation signal.
