Members of atRNA Gly 1 multigene family from the silkwormBombyx mori have been classified based on their transcriptions in homologous nuclear extracts, into three groups of highly, moderately and poorly transcribed genes. Because all these gene copies have identical coding sequences and consequently identical promoter elements (the A and B boxes), the flanking sequences modulate their expression levels. Here we demonstrate the inter-action of transcription factor TFIIIB with these genes and its role in regu-lating differential transcriptions....
