Human chorionic gonadotropin alpha and human cytomegalovirus promoters are extremely active in the fission yeast Schizosaccharomyces pombe.
We have investigated the transcriptional activity of human cytomegalovirus, herpes thymidine kinase, human chorionic gonadotropin alpha, somatostatin, immunoglobulin kappa chain, alpha crystallin, albumin and interferon-beta promoters in the fission yeast Schizosaccharomyces pombe. Among these, the human cytomegalovirus, human chorionic gonadotropin alpha, and somatostatin promoters were found to be very active, approximately 11-, 9-, and 0.9-fold as active as the SV40 early promoter, respectively. The remainder of the promoters studied were weak, having only 10-20% of the SV40 promoter activity. Primer extension analysis showed that the strong promoters initiated transcription in S. pombe at the same sites as in mammalian cells, indicating the high similarity between both transcriptional systems.
