| Post Translational Modifications | Ubiquitinated.undergoes 'Lys-63' monoubiquitination and diubiquitination by NEDD4. Multiple lysine residues are probably modified. Ubiquitination requires TNIK, prevents interaction with effectors and inactivates RAP2A. Palmitoylated. Palmitoylation is required for association with recycling endosome membranes and activation of TNIK. (Microbial infection) Glucosylated at Thr-35 by C.difficile toxin TcdA in the colonic epithelium, and by P.sordellii toxin TcsL in the vascular endothelium. |
| Function | Small GTP-binding protein which cycles between a GDP-bound inactive and a GTP-bound active form. In its active form interacts with and regulates several effectors including MAP4K4, MINK1 and TNIK. Part of a signaling complex composed of NEDD4, RAP2A and TNIK which regulates neuronal dendrite extension and arborization during development. More generally, it is part of several signaling cascades and may regulate cytoskeletal rearrangements, cell migration, cell adhesion and cell spreading. |
