Structural highlights
Function
[GNDS_HUMAN] Stimulates the dissociation of GDP from the Ras-related RalA and RalB GTPases which allows GTP binding and activation of the GTPases. Interacts and acts as an effector molecule for R-Ras, H-Ras, K-Ras, and Rap.

Publication Abstract from PubMed
The solution structure of the Ras-binding domain (RBD) of Ral guanine-nucleotide exchange factor RalGEF was solved by NMR spectroscopy. The overall structure is similar to that of Raf-RBD, another effector of Ras, although the sequence identity is only 13%. 15N chemical shifts changes in the complex of RalGEF-RBD with Ras indicate an interaction similar to the intermolecular beta-sheet observed for the complex between Ras and Raf-RBD.
