New! It is possible to link to RNAcentral without knowing the RNAcentral accession using a URL in the following format:
https://rnacentral.org/link/<database>:<accession>
where database
is one of the RNAcentral Expert Databases,
and accession
is an identifier from that database (see examples below).
Both parameters are case-insensitive.
This functionality relies on the RNAcentral text search. If only 1 sequence matches the database and accession, then the link will redirect to that sequence. If several sequences match, then the link will show a search result listing all matching sequences.
Examples
Please use the following format to link to RNAcentral sequences:
https://rnacentral.org/rna/<RNAcentral identifier>/<NCBI taxonomy identifier>
The URL includes NCBI taxonomy identifiers, for example 9606 for Homo sapiens.
Either slash /
or underscore _
can be used as a separator:
Links without NCBI taxonomy identifiers show annotations from all species where the sequence was found.
You can optionally add RNAcentral logo before the link, for example:
Example code:
<p>
<img src="https://rnacentral.org/static/img/logo/rnacentral-logo.png" style="width: 16px; height: 16px; vertical-align: middle;">
<a href="https://rnacentral.org/rna/URS000075A546/9606">URS000075A546/9606</a>
</p>
RNAcentral logos are available in the Downloads section.
For a small number of sequences, you can find RNAcentral accessions using text search.
If you need to perform a large-scale mapping between RNAcentral identifiers and Expert Database accessions, please use the mapping files found in FTP archive:
Mapping between RNAcentral sequences and all Expert Databases in a single file: https://ftp.ebi.ac.uk/pub/databases/RNAcentral/current_release/id_mapping/
Mapping between RNAcentral sequences and each Expert Databases in separate files: https://ftp.ebi.ac.uk/pub/databases/RNAcentral/current_release/id_mapping/database_mappings/
You can link to a genome location of interest within the RNAcentral genome browser using links like this:
https://rnacentral.org/genome-browser?species=<species>&chromosome=<chromosome>&start=<start>&end=<end>
where:
<species>
- organism name (lowercase, spaces replaced with underscores as in Ensembl, for example: homo_sapiens or canis_lupus_familiaris)<chromosome>
- chromosome name in Ensembl format, for example 1
(not chr1
)<start>
and <end>
- genome coordinatesExample:
Example code:
<p>
<img src="https://rnacentral.org/static/img/logo/rnacentral-logo.png" style="width: 16px; height: 16px; vertical-align: middle;">
<a href="https://rnacentral.org/genome-browser?species=homo_sapiens&chromosome=X&start=73819307&end=73856333">Human XIST gene</a>
</p>
Databases integrated in RNAcentral can display an RNAcentral Expert Database badge:
Example code:
<a href="https://rnacentral.org">
<img src="https://rnacentral.org/static/img/logo/rnacentral-expert-database.svg" style="width: 140px">
</a>
The badge should link to the RNAcentral homepage or to the landing page of the member database within RNAcentral, such as https://rnacentral.org/expert-database/flybase or https://rnacentral.org/expert-database/gtrnadb.
Here are RNAcentral logo icons in different resolutions:
