Gene Ontology Molecular Function
Biochemical Activity (Ubiquitination)
An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.
Publication
Rictor forms a complex with Cullin-1 to promote SGK1 ubiquitination and destruction.
The Rictor/mTOR complex (also known as mTORC2) plays a critical role in cellular homeostasis by phosphorylating AGC kinases such as Akt and SGK at their hydrophobic motifs to activate downstream signaling. However, the regulation of mTORC2 and whether it has additional function(s) remain largely unknown. Here, we report that Rictor associates with Cullin-1 to form a functional E3 ubiquitin ligase. ...

Additional Notes
- To purify the Cullin-1/Rictor E3 ligase complex, 293T cells were transfected with vectors encoding HA-Cullin-1, Myc-Rictor (WT or T1135E), and Flag-Rbx1. The Cullin-1/Rictor (E3) complexes were purified from the whole cell lysates using HA-agarose beads. Purified, recombinant SGK protein (purchased from Genway) were incubated with purified Cullin-1/Rictor (E3) complexes in the presence of purified, recombinant active E1, E2 (UbcH5a and UbcH3), ATP and ubiquitin.

| SGK1 RICTOR | Affinity Capture-Western Affinity Capture-Western An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner identified by Western blot with a specific polyclonal antibody or second epitope tag. This category is also used if an interacting protein is visualized directly by dye stain or radioactivity. Note that this differs from any co-purification experiment involving affinity capture in that the co-purification experiment involves at least one extra purification step to get rid of potential contaminating proteins. | Low | - | BioGRID | - |
