Interactioni

Subunit structurei

Interacts with MDM2; this interaction stabilizes MDM2. Interaction with MDM2 occurs in the nucleoplasm and is triggered by a nucleolar release mechanism, such as mitosis-induced nucleolar disassembly. Indirectly interacts with TP53, via MDM2-binding (By similarity).By similarity

Domaini

The basic domain (B) allows nucleolar localization in the absence of GTP. The intermediate domain (I) inhibits nucleolar localization by the B domain and is required for exit from the nucleolus. Exit from the nucleolus to the nucleoplasm requires both the I and the acidic (A) domains, and may be triggered by GTP hydrolysis (By similarity).By similarity
In contrast to other GTP-binding proteins, this family is characterized by a circular permutation of the GTPase motifs described by a G4-G1-G3 pattern.

Belongs to the TRAFAC class YlqF/YawG GTPase family.PROSITE-ProRule annotation

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
