Exon Query Documentation

Any combination of fields may be entered to specify the desired query conditions.

Field Name Field Description
Data Source: Select one of four options for the origin of the data; the options are "mitochondrial", "chloroplast", "bacterial" or "all". Default value is "all".
Show Oversampled Data: In cases where GenBank contains more than five copies of the same gene from the same organism, we in GOBASE select the five most divergent copies as type examples. Selecting "Yes" here will display exons from all the copies of these genes; selecting "No" shows type examples only. Default value is "No".
Gene Name: Enter the name of the gene containing the exon here. Accepts * as an initial or terminal wildcard. A link is provided to a list of all gene and product names currently contained in GOBASE.
Taxon Name: Enter the taxon name here. Accepts * as an initial or terminal wildcard.
Taxon Division: Mark any of the boxes to receive results from that subset of taxon divisions; options are Fungi, Metazoa, Plants. Protista, α-proteobacteria, γ-proteobacteria and Cyanobasteria. Default behaviour with no boxes marked is to return data from all taxonomic divisions.
Exon Number: Specify the number of the exon within the gene.
Partial Exon: Select partial exons. Default value "not set".
Exon location on sequence
From: Specify position on sequence after which exon must start.
To: Specify position on sequence before which exon must end.
Strand: Specify strand on which the exon occurs.
Database-related Specifications
NCBI/Entrez GI Specify an NCBI "gi" identifier.
GenBank Accession: Specify a GenBank accession number.
GOBASE Feature ID: Specify a GOBASE feature ID for the exon.
Sort Results by: Specify the order in which the results will be sorted; options are by gene name or species name.
