Abstract:
We have previously reported that the chicken polyubiquitin gene UbII is preferentially expressed during spermatogenesis and we show here that UbII is the predominant polyubiquitin gene expressed in early embryogenesis. Two main initiation sites were detected. Transcription from the initiation site used in early embryos results in the presence of an intron in the 5'‐untranslated region of the transcripts as has been reported for other polyubiquitin messages. In mature testis, however, the use of a different initiation site, located within the intron, produces intronless transcripts. Distinct promoter sequences, present in each initiation site, may regulate the differential expression observed in this gene.
