FlyBase:Computed Feature type of genes

The Feature type field of a Gene Report contains a single controlled vocabulary term from the Sequence Ontology (SO), which aims to describe the key type of the gene.

The single term in this field is computed by FlyBase from the full list of SO terms listed in the SEQUENCE ONTOLOGY: Class of gene section of the Gene Report, according to the following rules:

  • If the gene is a "foreign" gene (a gene that is derived from a species outside the family Drosophilidae, but has been analysed in Drosophila), the relevant SO term - e.g. engineered_foreign_gene - is displayed in the Feature type section, regardless of any other terms in the list.
  • if the gene represents an engineered object, for example a fusion gene between two D>melanogaster genes, the relevant SO term - e.g. engineered_fusion_gene - is displayed in the Feature type section, regardless of any other terms in the list.
  • if the gene represents a natural transposon, or a gene encoded by a natural transposon, the relevant SO term - e.g. transposable_element - is displayed in the Feature type section, regardless of any other terms in the list.
  • if the gene is a pseudogene, the relevant SO term - pseudogene_attribute - is displayed in the Feature type section, regardless of any other terms in the list.
  • if a SO term which describes what type of molecule the gene encodes has been assigned to the gene - e.g. miRNA_gene, tRNA_gene or protein_coding_gene - that SO term is displayed in the Feature type section, regardless of any other terms in the list.
