We have mapped the only transcription unit known to be present in the C-8 DNA puff of Rhynchosciara americana and describe the isolation and sequence of a cDNA clone, pRa C-8-22, which contains a nearly complete copy of the mRNA transcribed from this DNA puff and part of the sequence of genomic clone BSC8-0.9, which contains the promoter region and the remainder of the transcription unit. The characteristics of the protein predicted from the ORF present in the cDNA indicate that it is unique and secreted.
