Transfer-messenger RNA databases | Non-coding transcript data analysis
The transfer-messenger RNA (tmRNA) and its partner protein SmpB act together in resolving problems arising when translating bacterial ribosomes reach the end of mRNA with no stop codon. Their genes have been found in nearly all bacterial genomes and in some organelles.
Provides a collection of noncoding RNA sequences. Rfam is an online resource where RNA sequences are grouped into “families” and “clans” on the basis of nucleotide sequence and secondary structure homology. It includes many different types of ncRNA genes, cisregulatory elements and intronic elements, all annotated in as many species as possible. This database is searched for homologous sequences.
Collects ncRNA sequences from a broad range of species. RNAcentral gives access to data, search functionality, cross-references, source code and an integrated genome browser for selected species. It integrates genomic locations for sequences in selected model organisms, quality control information for all sequences, functional and structural annotations, and miRNA targets. This platform can assist users to discover the correct miRNA identifier.
Contains predicted tmRNA sequences from RefSeq prokaryotic genomes, plasmids and phages. New features include software used to find the sequences, an update raising the number of unique tmRNA sequences from 492 to 1716, and a database of SmpB sequences which are served along with the tmRNA sequence from the same organism.
A tool in the study of the structures and functions of the tmRNA (earlier called "10S RNA"). tmRDB provides links to high-resolution structures and serve as depositories for structures obtained by molecular modeling.
