This reference is used to assign the 'protein_coding_gene' class (Sequence Ontology ID SO:0000010) to a Drosophila gene that meets the following criteria:
- it currently lacks the 'protein_coding_gene' annotation in FlyBase
- it is associated with a UniProt ID (i.e. there is evidence that the gene encodes a protein product)
- it is not classed as a pseudogene or non-coding RNA gene in FlyBase
- its 'gene model status' in FlyBase is not 'withdrawn' (i.e. it has not had its gene model removed based on a manual assessment of evidence)
