Abstract

Presently, nothing is known about the function of the Ras-related protein Rheb. Since Rheb shares significant sequence identity with the core effector domains of Ras and KRev-1/Rap1A, it may share functional similarities with these two structurally related, yet functionally distinct, small GTPases. Furthermore, since like Ras, Rheb terminates with a COOH terminus that is likely to signal for farnesylation, it may be a target for the farnesyltransferase inhibitors that block Ras processing and function. To compare Rheb function with those of Ras and KRev-1, we introduced mutations into Rheb that generate constitutively active or dominant negative forms of Ras and Ras-related proteins and were designated Rheb(64L) and Rheb(20N), respectively. Expression of wild type or mutant Rheb did not alter the morphology or growth properties of NIH 3T3 cells. Thus, aberrant Rheb function is distinct from that of Ras and fails to cause cellular transformation. Instead, similar to KRev-1, co-expression of Rheb antagonized oncogenic Ras transformation and signaling. In vitro and in vivo analyses showed that like Ras, Rheb proteins are farnesylated and are sensitive to farnesyltransferase inhibition. Thus, it is possible that Rheb function may be inhibited by farnesyltransferase inhibitors treatment and, consequently, may contribute to the ability of these inhibitors to impair Ras transformation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
