domain: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.,domain: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.,function:May be required to maintain the proliferative capacity of stem cells and may play an important role in tumorigenesis.,similarity:Belongs to the MMR1/HSR1 GTP-binding protein family.,subcellular location:Shuttles between the nucleus and nucleolus.,subunit:May interact with p53/TP53 via its basic domain.,tissue specificity:Increased levels in lung tissue in cancer patients.,
