General info

Function

Involved in the activation of Ras protein signal transduction (PubMed : 22821884). Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (PubMed : 12740440, PubMed : 14500341, PubMed : 9020151).

Sequence similarities

Belongs to the small GTPase superfamily. Ras family.

Post-translational modifications

Palmitoylated by the ZDHHC9-GOLGA7 complex. A continuous cycle of de- and re-palmitoylation regulates rapid exchange between plasma membrane and Golgi.. S-nitrosylated; critical for redox regulation. Important for stimulating guanine nucleotide exchange. No structural perturbation on nitrosylation.. The covalent modification of cysteine by 15-deoxy-Delta12,14-prostaglandin-J2 is autocatalytic and reversible. It may occur as an alternative to other cysteine modifications, such as S-nitrosylation and S-palmitoylation.. Acetylation at Lys-104 prevents interaction with guanine nucleotide exchange factors (GEFs).. Fatty-acylated at Lys-170.. Ubiquitinated by the BCR(LZTR1) E3 ubiquitin ligase complex at Lys-170 in a non-degradative manner, leading to inhibit Ras signaling by decreasing Ras association with membranes.. (Microbial infection) Glucosylated at Thr-35 by P.sordellii toxin TcsL (PubMed:19744486, PubMed:8626575, PubMed:8626586, PubMed:9632667). Monoglucosylation completely prevents the recognition of the downstream effector, blocking the GTPases in their inactive form, leading to inhibit Ras signaling (PubMed:8626575, PubMed:8626586, PubMed:9632667).
