Database selection dialog for fetching sequences (introduced in Jalview 2.8)

Two types of ENSEMBL source are provided. ENSEMBL queries the - main ENSEMBL site, which only serves data for higher eukaryotes, and - EnsemblGenomes, which provides access to Ensembl Pathogens, and - other warehouses.

General Use
If you have a set of Ensembl - peptide or transcript IDs, then you can retrieve them - via the sequence fetcher dialog opened after selecting the - most appropriate source (either 'ENSEMBL', or Ensembl Genomes). - However, Jalview's Ensembl client has a couple of additional - capabilities:

Retrieving aligned transcripts for a genomic ID -

If a single genomic identifier is entered in the - Ensembl fetcher, Jalview will return all transcripts and products - for the locus, and display them in a split view - complete with - sequence variant annotation.

Retrieving orthologs for a gene ID

If a gene ID is entered (e.g. fox1), Jalview will resolve - Ensembl genomic identifiers for a predefined set of taxa (Mouse, - Rat, Human, Yeast in Jalview 2.10). -

+ Ensembl Sequence + Features
Jalview 2.10 includes support for the + visualisation and transfer genomic and transcriptomic sequence + features onto protein product sequences. Retrieval of a genomic + locus results in a set of transcripts that are annotated with + nucleotide variant information and exonic regions. By default, + intronic regions will be hidden. +

+ Variant information on + Protein Products
Jalview can translate genomic variant + annotation into protein sequence variant codes for variants + intersecting coding regions of a gene. To see this in action, use + the Calculate→Show cross-references menu to + view protein product sequences for the currently displayed (or + selected) sequences. The same menu allows you to recover Ensembl + exon, transcript and variant information when viewing UniProt + sequences. +

+ Viewing more information about variant annotation
+ Variants are highlighted as red sequence features on the protein + sequence, with each one reporting all protein sequence variants + observed at that position as a result of the genomic variants. + Right-clicking a variant allows you to open the Ensembl Variants web + page for each variant, via the Link submenu. +

+ Work in Progress !
In the next few releases, + we hope to improve and extend Jalview's support for working with + Ensembl. If you have any problems, questions or suggestions then + please get in contact with us via the Jalview discussion list. +
