The Ras-related protein Rheb is farnesylated and antagonizes Ras signaling and transformation.
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 fa...
متن کاملRas-GRF activates Ha-Ras, but not N-Ras or K-Ras 4B, protein in vivo.
Human cells contain four homologous Ras proteins, but it is unknown whether these homologues have different biological functions. As a first step in determining if Ras homologues might participate in distinct signaling cascades, we assessed whether a given Ras guanine nucleotide exchange factor could selectively activate a single Ras homologue in vivo. We found that Ras-GRF/Cdc25Mm activates Ha...
متن کاملPPP1CA contributes to the senescence program induced by oncogenic Ras.
Ectopic expression of conditional murine p53 (p53val135) and oncogenic ras is enough to induce a senescent-like growth arrest at the restrictive temperature. We took advantage of this cellular system to identify new key players in the ras/p53-induced senescence. Applying a retroviral-based genetic screen, we obtained an antisense RNA fragment against PPP1CA, the catalytic subunit of protein pho...
متن کاملRas effectors: Buying shares in Ras plc
The debate over whether activated Ras can regulate phosphoinositide-specific phospholipase C (PLC) has been contentious and at times heated. The argument may be resolved by the recent identification of a novel Ras-regulated PLC, but some unexpected properties of this protein are sure to stimulate further controversy.
متن کاملK-ras is an essential gene in the mouse with partial functional overlap with N-ras.
Mammalian ras genes are thought to be critical in the regulation of cellular proliferation and differentiation and are mutated in approximately 30% of all human tumors. However, N-ras and H-ras are nonessential for mouse development. To characterize the normal role of K-ras in growth and development, we have mutated it by gene targeting in the mouse. On an inbred genetic background, embryos hom...
