Cytoplasmic ribosomal protein genes of the fission yeast Schizosaccharomyces pombe display a unique promoter type: a suggestion for nomenclature of cytoplasmic ribosomal proteins in databases.

We identified 34 new ribosomal protein genes in the Schizosaccharomyces pombe database at the Sanger Centre coding for 30 different ribosomal proteins. All contain the Homol D-box in their promoter. We have shown that Homol D is, in this promoter type, the TATA-analogue. Many promoters contain the Homol E-box, which serves as a proximal activation sequence. Furthermore, comparative sequence analysis revealed a ribosomal protein gene encoding a protein which is the equivalent of the mammalian ribosomal protein L28. The budding yeast Saccharomyces cerevisiae has no L28 equivalent. Over the past 10 years we have isolated and characterized nine ribosomal protein (rp) genes from the fission yeast S.pombe . This endeavor yielded promoters which we have used to investigate the regulation of rp genes. Since eukaryotic ribosomal proteins are remarkably conserved and several rp genes of the budding yeast S.cerevisiae were sequenced in 1985, we probed DNA fragments encoding S.cerevisiae ribosomal proteins with genomic libraries of S.pombe . The deduced amino acid sequence of the different isolated rp genes of fission yeast share between 65 and 85% identical amino acids with their counterparts of budding yeast.

[Cytoplasmic islet-cell antibodies (ICA) and cytoplasmic complement- fixing antibodies (CF-ICA) in patients with newly detected and short-lasting diabetes mellitus type 1].

The study aimed at assessing ICA and CF-ICA in the serum of patients with newly diagnosed and short-lasting diabetes mellitus type 1. Sixty patients with newly diagnosed diabetes type 1 (39 patients) and short-lasting diabetes of the same type (21 patients) aged between 2 and 34 years were classified. Anti-islet antibodies were detected with indirect immunoflourescence in specimens of fresh, frozen human pancreast in the tested group ICA were found in 53% of cases. At the time of diagnosis, ICA were found in 76% of children and in 14% of adult patients whereas respective data for diabetes mellitus lasting up to 2 years were 40% and 64%. Complement-fixing islet cytoplasmatic antibodies were found only in patients with ICA (47% of such cases). These antibodies were found in children with newly diagnosed diabetes mellitus (36%). In case of adults CF-ICA were detected in 7% of newly diagnosed diabetes mellitus cases and in 45% of cases with the disease lasting for 2 years. Titres of ICA ranged from 1:1 to 1:128 whereas titres CF-ICA from 1:1 to 1:8. No correlation between ICA titre and CF-ICA titre was noted.
