What's a GeneRIF?

Prat2 is required during the prepupal stage while Prat is more important for the pupal stage; Prat2 is essential for fly development.
Title: The purine synthesis gene Prat2 is required for Drosophila metamorphosis, as revealed by inverted-repeat-mediated RNA interference.
Evidence suggests that Prat originated by gene duplication by retrotransposition of Prat2.
Title: The PRAT purine synthesis gene duplication in Drosophila melanogaster and Drosophila virilis is associated with a retrotransposition event and diversification of expression patterns.
