The gene Ras homolog enriched in brain ortholog (H. sapiens) is referred to in FlyBase by the symbol Dmel\Rheb (CG1081, FBgn0041191). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: protein binding; GTPase activity. There is experimental evidence for 13 unique biological process terms, many of which group under: biological regulation; cellular component organization or biogenesis; growth; single-organism developmental process; developmental growth; positive regulation of ribosome biogenesis; energy taxis; response to nutrient levels; cell cycle; response to light stimulus; response to starvation; cell cycle process; ribosome biogenesis; positive regulation of cellular biosynthetic process. 34 alleles are reported. The phenotypes of these alleles are annotated with: organ system; organ system subdivision; multicellular structure; cell cycle; adult segment; external compound sense organ; cellular process; adult; cell cycle process; peripheral nervous system. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: Small GTP-binding protein domain; Small GTPase superfamily; Small GTPase superfamily, Ras type. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderately high expression. Peak expression observed at stages throughout embryogenesis, during late larval stages, during early pupal stages, in stages of adults of both sexes. Summary of FlyAtlas Anatomical Expression Data: High or moderate levels of expression observed in all larval and adult organs/tissues. Expression at high levels in the following post-embryonic organs or tissues: adult head, adult eye, adult crop, adult midgut, larval/adult Malpighian tubules, adult heart, adult salivary gland, larval trachea, adult spermathecae, adult male accessory gland. Expression at moderate levels in the following post-embryonic organs or tissues: larval/adult central nervous system, larval midgut, larval/adult hindgut, larval/adult fat body, larval salivary gland, adult ovary, adult testis, larval/adult carcass.

RNAi screen using dsRNA made from templates generated with primers directed against this gene results in chromosome misalignment on the metaphase spindle when assayed in S2 cells in the presence of Cdc27 dsRNA. This phenotype cannot be observed when the screen is performed without Cdc27 dsRNA.
dsRNA made from templates generated with primers directed against this gene results in a reduced mean cell diameter. Silencing Rheb generates a cell-expression profile similar to that of rapamycin-treated cells.
dsRNA made from templates generated with primers directed against this gene promotes the phosphorylation of Akt1 (dependent on TORC2) and inhibits phosphorylation of S6k in S2 cells. In addition, knockdown of Rheb enhances insulin-stimulated Akt1 phosphorylation.
Signaling through Tor and its upstream regulators Pi3K92E/Pi3K21B and Rheb is necessary and sufficient to suppress starvation-induced autophagy in the fat body.
In mitotic tissues, overexpression of Rheb accelerates passage through G1-S phase without affecting rates of cell division, whereas in endoreplicating tissues, overexpression increases DNA ploidy. Overexpression of Rheb can also drive cell growth in starved animals.
