Welcome to Transterm, a database providing access to mRNA sequences and associated regulatory elements. A new feature (5/2014) is to analyse a human 3' UTR alignment to predict both protein and miRNA binding sites (go to Scan for Motifs).

The mRNA sequences are processed from Genbank, including complete genomes. They are divided into biologically relevant sections 5' UTRs and 3' UTRs, initiation and termination regions and the full CDS sequences.

This data or your own sequences can be searched for defined regulatory elements (e.g. Puf3, Iron Responsive Element). The Transterm elements were updated (5/2014)here.

A more detailed overview is found in our publication "Transterm: a database to aid the analysis of regulatory sequences in mRNAs"in Nucleic Acids Research.

What can be done here?

Obtain data relating to translation, by species in a non-redundant format: for example bias around initiation and termination codons, or codon usage (more...).

Search for regulatory elements in a defined set - for example known or putative mRNA stability or localisation elements in 3'UTRs (more...).

Search your own sequence for known regulatory elements (more...).

Quick guide - how to use the database

This database contains data related to specific species and strains through NCBI TaxIDs, the initial default is Homo Sapiens (9606).

1) For the species many types of pre-processed data are available, differing in experimental support and redundancy. For completed genomes the most useful files are likely to be 'NCBI-Genomes - one sequence for each coding region' (more...)

2) Choose your TaxID species or strain (example...).

3) This data can be analysed for known or putative regulatory elements (more...). More about regulatory elements in mRNAs.

Alternative ways of using the database

Get descriptions of regulatory elements (example...).

Search the data using BLAST (search).

2. Search for regulatory elements in specific regions:

... stop signal

  Init. region       Term. region  
  5' flank           3' flank  
Search  Non-redundant sequences (criteria) or  all sequences.

3. Or search your own sequence for regulatory elements

This tool has been superceded (5/2014) by Scan for Motifs- use that for new analyses. This legacy tool will continue to be available for 12 months- it is using an older version of the TransTerm regulatory element descriptions (from 5/2013).

The TransTerm entries have also been updated access them through Scan for Motifs.

Note: The default search is for those patterns without 'False positive' warnings:

Use FASTA format, max. size 30,000 e.g.:
> My mRNA

Search program to use:

Alternatively, use a BLAST (search).
