This paper presents the updated version (Y2K) of the database of ribosomal 5S ribonucleic acids (5S rRNA) and their genes (5S rDNA), http://rose.man/poznan.pl/5SData/index.html. This edition of the database contains 1985primary structures of 5S rRNA and 5S rDNA. They include 60 archaebacterial, 470 eubacterial, 63 plastid, nine mitochondrial and 1383(More)
BACKGROUND MicroRNAs (miRNAs) are important genetic elements that regulate the expression of thousands of human genes. Polymorphisms affecting miRNA biogenesis, dosage and target recognition may represent potentially functional variants. The functional consequences of single nucleotide polymorphisms (SNPs) within critical miRNA sequences and outside of(More)
In last few years much data has accumulated on various non-translatable RNA transcripts that are synthesised in different cells. They are lacking in protein coding capacity and it seems that they work mainly or exclusively at the RNA level. All known non-coding RNA transcripts are collected in the database: http://www. man.poznan.pl/5SData/ncRNA/index.html
It is now becoming evident that the variety of noncoding RNA (ncRNA) molecules play important roles in many cellular processes and they are not just mere intermediates in transfer of genetic information from DNA to proteins. Recent data, from the analyses of transcriptional activity of human genome, suggest that it may contain roughly equal numbers of(More)
Ribosomal 5S RNA (5S rRNA) is an integral component of the large ribosomal subunit in all known organisms with the exception only of mitochondrial ribosomes of fungi and animals. It is thought to enhance protein synthesis by stabilization of a ribosome structure. This paper presents the updated database of 5S rRNA and their genes (5S rDNA). Its short(More)
The non-coding RNAs database (http://biobases.ibch.poznan.pl/ncRNA/) contains currently available data on RNAs, which do not have long open reading frames and act as riboregulators. Non-coding RNAs are involved in the specific recognition of cellular nucleic acid targets through complementary base pairing to control cell growth and differentiation. Some of(More)
In last few years much data has accumulated which shows that in different cells various RNA transcripts are synthesized. They lack protein coding capacity and do not produce mature protein. It seems that they work mainly or exclusively on the RNA level. Their function and mechanism of action is poorly understood. In this paper we have collected all known(More)
The noncoding RNAs database is a collection of currently available sequence data on RNAs, which have no protein-coding capacity and have been implicated in regulation of cellular processes. The RNAs included in the database form very heterogenous group of molecules that act on different levels of information transmission in the cell. It includes RNAs acting(More)
This is an update for the 5S rRNA sequences of the BERLIN RNA DATABANK last published in 1990 (1). The new entry consists of 25 eubacterial and 2 eukaryotic 5S rRNA sequences and 10 plant 5S rRNA pseudogenes (Table 1). Thus the BERLIN RNA DATABANK contains as of February 1, 1991 the 5S rRNA sequences of 44 archaebacteria, 292 eubacteria, 20 plastids, 6(More)
In this paper we present the updated version of the compilation of 5S rRNA and 5S rDNA nucleotide sequences. It contains 1622 primary structures of 5S rRNAs and 5S rRNA genes from 888 species. These include 58 archaeal, 427 eubacterial, 34 plastid, nine mitochondrial and 1094 eukaryotic DNA or RNA nucleotide sequences. The sequence entries are divided(More)
