The gene raspberry is referred to in FlyBase by the symbol Dmel\ras (CG1799, FBgn0003204). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: IMP dehydrogenase activity. There is experimental evidence that it is involved in the biological process: axon guidance; phagocytosis, engulfment. 84 alleles are reported. The phenotypes of these alleles are annotated with: macrochaeta; pigment cell. It has 5 annotated transcripts and 5 annotated polypeptides. Protein features are: Aldolase-type TIM barrel; Cystathionine beta-synthase, core; IMP dehydrogenase / GMP reductase, conserved site; IMP dehydrogenase/GMP reductase; Inosine-5'-monophosphate dehydrogenase. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression. Peak expression observed within 00-06 hour embryonic stages, at stages throughout the larval period, during early pupal stages, in adult female stages. Summary of FlyAtlas Anatomical Expression Data: Nearly all larval and adult organs/tissues expressed at moderate or high levels. Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, larval/adult central nervous system, larval hindgut, larval/adult Malpighian tubules, larval/adult fat body, larval salivary gland, larval trachea, adult female reproductive system, adult male accessory gland, larval carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult brain, adult crop, larval/adult midgut, adult hindgut, adult heart, adult salivary gland, adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1627916_s_at completely aligns to an exonic region common to each of the 3 FlyBase-annotated transcript isoforms of ras. Gene sequence location is X:10638535..10642848.

& Zimm 1992)
Gene/Allele symbols may differ
from current usage
ras: raspberry
Defective in pteridine synthesis; eye color dark
ruby. Appears to affect the level of guanosine triphosphate
cyclohydrolase activity; ras alleles exhibit increased
activity compared to wild type at pupariation, but decreased
activity at eclosion (Evans and Howell, 1979, Biochem. Genet.
16: 13-26). Not a purine auxotroph. Color autonomous in larval optic disks transplanted into wild-type hosts (Beadle and
Ephrussi, 1936, Genetics 21: 230). ras/rasl display ras eye
color. Larval Malpighian tubes nearly wild type; not useful
for classification (Brehme and Demerec, 1942, Growth 6: 351-56). ras is but one of four types of mutations belonging to
an interrelated complex involved some way in purine metabolism: ras, a nonauxotrophic eye-color mutant; two purine auxotrophs, pur1 and gua1, which complement ras and one another;
and rasl, lethal alleles that fail to complement completely
the other three types. The complex shares genetic features
with rudimentary.

There is a discrepancy between the in situ localisation (7E3--7E6) and the molecular localisation based on the flanking sequence (9E2--9E4) for the "l(1)G0238" (rasG0238) line. The available data suggests that it is most likely that the molecular localisation (9E2--9E4) is correct and that the in situs were misinterpreted.
Summary of FlyAtlas Anatomical Expression Data: Nearly all larval and adult organs/tissues expressed at moderate or high levels.

Mutant analysis suggests that GMP synthesis from IMP is an essential process, and that activity of the ras gene product, IMPDH, is regulated in a tissue-specific manner.
ras is but one of four types of mutations belonging to an interrelated complex involved some way in purine metabolism: ras, a nonauxotrophic eye-color mutant; two purine auxotrophs, pur1 and gua1, which complement ras and one another; and ras lethal alleles that fail to complement completely the other three types. The complex shares genetic features with r.
Defective in pteridine synthesis; eye color dark ruby. Appears to affect the level of guanosine triphosphate cyclohydrolase activity; ras alleles exhibit increased activity compared to wild type at pupariation, but decreased activity at eclosion (FBrf0031059). Not a purine auxotroph. Color autonomous in larval optic discs transplanted into wild-type hosts (FBrf0003530). ras1/ras-lethal display ras eye color. Larval Malpighian tubes nearly wildtype; not useful for classification FBrf0005752).
The different temperature sensitive periods for the ras gene product, demonstrated with the rasl1 mutation, indicate tissue-specific activation of a gene at different times during development, although the possibility of activation of preformed polypeptides has not been eliminated.
