Summary: Enables amidophosphoribosyltransferase activity. Involved in several processes, including determination of adult lifespan; embryonic cleavage; and purine nucleotide biosynthetic process. Is expressed in several structures, including follicle cell; germline cell; gonad; gut section; and somatic trunk mesoderm derivative. Orthologous to human PPAT (phosphoribosyl pyrophosphate amidotransferase). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

DREF binds directly upstream of Prat and the DRE sites associated with its activity are necessary for Prat expression
Title: Transcriptional regulation of the purine de novo synthesis gene Prat in Drosophila melanogaster.
Data show the presence of apoptosis at the cellular level in both ade2 and Prat mutants, and the upregulated gene HtrA2, which encodes an apoptosis effector and is thus a candidate for initiating apoptosis in response to purine depletion.
Title: A link between impaired purine nucleotide synthesis and apoptosis in Drosophila melanogaster.
whereas Mod(Prat:bw)3-5 suppresses Prat in all stages and tissues examined for both sexes.
Title: Modifiers of Prat, a de novo purine synthesis gene, in Drosophila melanogaster.
Use of Prat and Prat2 double RNA interference causes more severe pupal lethal phenotypes and suggests that Prat and Prat2 have partially additive functions during Drosophila metamorphosis.
Title: The purine synthesis gene Prat2 is required for Drosophila metamorphosis, as revealed by inverted-repeat-mediated RNA interference.
Data show that the requirement for both Prat and Prat2 in Drosophila is not simply due to differences in protein function. Both genes have developed nonoverlapping patterns of expression, which correlate with their respective loss-of-function phenotypes.
Title: Expression pattern diversity and functional conservation between retroposed PRAT genes from Drosophila melanogaster and Drosophila virilis.
Regulation of expression of prat in the adult eye was studied.
Title: Identification of trans-dominant modifiers of Prat expression in Drosophila melanogaster.
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.
limiting factor in the processes of cellular or nuclear proliferation that take place during egg chamber and embryonic development
Title: Drosophila melanogaster Prat, a purine de novo synthesis gene, has a pleiotropic maternal-effect phenotype.
