Linking to sequences

Link by external accession

New! It is possible to link to RNAcentral without knowing the RNAcentral accession using a URL in the following format:<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.


Direct link format

Please use the following format to link to RNAcentral sequences:<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:

  <img src="" style="width: 16px; height: 16px; vertical-align: middle;">
  <a href="">URS000075A546/9606</a>

RNAcentral logos are available in the Downloads section.

Mapping between third-party identifiers and RNAcentral IDs

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:

Linking to genome locations

You can link to a genome location of interest within the RNAcentral genome browser using links like this:<species>&chromosome=<chromosome>&start=<start>&end=<end>


  • <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 coordinates


Human XIST gene

Example code:

  <img src="" style="width: 16px; height: 16px; vertical-align: middle;">
  <a href="">Human XIST gene</a>


RNAcentral Expert Database badge

Databases integrated in RNAcentral can display an RNAcentral Expert Database badge:

Example code:

<a href="">
  <img src="" style="width: 140px">

The badge should link to the RNAcentral homepage or to the landing page of the member database within RNAcentral, such as or
