[https://www.uniprot.org/uniprot/RAN_HUMAN RAN_HUMAN] GTP-binding protein involved in nucleocytoplasmic transport. Required for the import of protein into the nucleus and also for RNA export. Involved in chromatin condensation and control of cell cycle (By similarity). The complex with BIRC5/ survivin plays a role in mitotic spindle formation by serving as a physical scaffold to help deliver the RAN effector molecule TPX2 to microtubules. Acts as a negative regulator of the kinase activity of VRK1 and VRK2.<ref>PMID:10400640</ref> <ref>PMID:8692944</ref> <ref>PMID:18591255</ref> <ref>PMID:18617507</ref> Enhances AR-mediated transactivation.

== Publication Abstract from PubMed ==
 +
Classic nuclear export signals (NESs) confer CRM1-dependent nuclear export. Here we present crystal structures of the RanGTP-CRM1 complex alone and bound to the prototypic PKI or HIV-1 Rev NESs. These NESs differ markedly in the spacing of their key hydrophobic (Phi) residues, yet CRM1 recognizes them with the same rigid set of five Phi pockets. The different Phi spacings are compensated for by different conformations of the bound NESs: in the case of PKI, an alpha-helical conformation, and in the case of Rev, an extended conformation with a critical proline docking into a Phi pocket. NMR analyses of CRM1-bound and CRM1-free PKI NES suggest that CRM1 selects NES conformers that pre-exist in solution. Our data lead to a new structure-based NES consensus, and explain why NESs differ in their affinities for CRM1 and why supraphysiological NESs bind the exportin so tightly.
