The Sequence Feature Report contains the information for an individual sequence feature mapped to the genome. This is a field-by-field guide to the information provided in the Sequence Feature Report.
Both endogenous features and reagent features are included in the Sequence Feature data class. Endogenous DNA features include: TF_binding_site, protein_binding_site, transcription_start_site, origin_of_replication, regulatory_region, enhancer, silencer, insulator. Features of RNAs that overlap a particular genomic site are also captured in this report format, for example, exon_junction (based on RNASeq), and modified_RNA_base_feature (A-to-I editing site). Reagent features include RNAi_reagent and transgenic enhancer candidates (classified as “region”).
PLEASE NOTE: The appearance of the Sequence Feature Report will vary for different kinds of features. In part this is because fields that contain no data for that specific sequence feature may not be displayed in the Sequence Feature Report. In part this is due to JBrowse views that are customized to the feature type.
FlyBase attributes data to the publication that reported it, so that users can easily refer back to the original publication if they wish. Thus, where possible in the fields below, the publication(s) that are the source of the information are listed, typically in parentheses to the right of the data.
General Information
| Symbol | The valid symbol that is used in FlyBase. |
| Species | The organism that the sequence feature originates from, with the initial letter of the genus and the full species name listed. |
| Feature Type | The type of sequence feature described in the report. |
| FlyBase ID | The Primary FlyBase identifier number of the sequence feature, used to uniquely identify the sequence feature in the database.
A sequence feature may also have any number of Secondary FlyBase identifier numbers, which are listed in the Secondary FlyBase IDs section of the Sequence feature Report. |
| Collection | The large scale dataset or reagent collection of which this sequence feature is a member. |
| Associated gene(s) | Genes associated with this sequence feature. |
Genomic Location
| Chromosome Arm | The chromosome arm that the sequence is located on. |
| Sequence location | The genomic location of the sequence feature: arm:start..stop [strand]. |
| Map | A JBrowse thumbnail showing the sequence feature (highlighted in yellow) in relation to other genes and sequence features; the other types of data shown for context will depend on the sequence feature type. Links at the far left provide views of the feature in JBrowse. |
Recent Updates
This section contains items that were added to this record for each release. It currently only tracks new links between this FlyBase report and other FlyBase data classes (e.g. genes, references, stocks) or controlled vocabulary terms (e.g. GO, anatomy terms).
