Abstract: Messenger RNAs, in addition to coding for proteins, may contain regulatory elements that affect how the protein is translated. These include protein and microRNA-binding sites. Transterm (http://mRNA.otago.ac.nz/Transterm.html) is a database of regions and elements that affect translation with two major unique components. The first is integrated results of analysis of general features that affect translation (initiation, elongation, termination) for species or strains in Genbank, processed through a standard pipeline. The second is curated descriptions of experimentally determined regulatory elements that function as translational control elements in mRNAs. Transterm focuses on protein binding sites, particularly those in 3'-untranslated regions (3'-UTR). For this release the interface has been extensively updated based on user feedback. The data is now accessible by strain rather than species, for example there are 10 Escherichia coli strains (genomes) analysed separately. In addition to providing a repository of data, the database also provides tools for users to query their own mRNA sequences. Users can search sequences for Transterm or user defined regulatory elements, including protein or miRNA targets. Transterm also provides a central core of links to related resources for complementary analyses.

Abstract: Transterm has now been publicly available for >10 years. Major changes have been made since its last description in this database issue in 2002. The current database provides data for key regions of mRNA sequences, a curated database of mRNA motifs and tools to allow users to investigate their own motifs or mRNA sequences. The key mRNA regions database is derived computationally from Genbank. It contains 3' and 5' flanking regions, the initiation and termination signal context and coding sequence for annotated CDS features from Genbank and RefSeq. The database is non-redundant, enabling summary files and statistics to be prepared for each species. Advances include providing extended search facilities, the database may now be searched by BLAST in addition to regular expressions (patterns) allowing users to search for motifs such as known miRNA sequences, and the inclusion of RefSeq data. The database contains >40 motifs or structural patterns important for translational control. In this release, patterns from UTRsite and Rfam are also incorporated with cross-referencing. Users may search their sequence data with Transterm or user-defined patterns. The system is accessible at http://uther.otago.ac.nz/Transterm.html.

Abstract: Transterm is a database that facilitates studies of translation and the translational control of protein synthesis. It contains a curated collection of elements in mRNAs that control translation, and biologically relevant mRNA regions extracted from GenBank. It is organised largely on a taxonomic basis with files and summaries for each species. Global patterns that may affect translation in particular species, for example bias in the context of initiation codons (Kozak's consensus or Shine-Dalgarno sequences) or termination codons, can be detected in the consensus and information content bias summaries. Several types of access are provided via a web browser interface. Transterm defined elements may be matched in a user's sequence or in the database. Alternatively, elements can be entered by the user to search specific sections of the database (for example, coding regions or 3' flanking regions or the 3'-UTRs) or the user's sequence. Each Transterm defined element has an associated biological description with references. The database is accessible at http://uther.otago.ac.nz/Transterm.html.
