Comments
GNL3L is a putative GTPase found in the nucleolus which is thought to have functions in regulating cell-cycle progression and cell proliferation. Thoompumkal et al. found that the protein is mislocalized when GTP synthesis is inhibited or when nucleolar localization signal is deleted. The study showed that nuclear export is CRM1-dependent and region 501-582 is sufficient for export activity. Binding to CRM1 was shown by co-IP. Putative NES was identified in 561-572 which matches traditional NES consensus and mutations to M567, L570 and L572 abolished export activity.

User Input
Accurate identification of NESs is difficult because many sequences in the genome match the NES consensus. Therefore, some published NESs may be mistakenly identified. Please help us improve the accuracy of NESdb by providing either a positive or negative flag for the NES in this entry. Supporting comments are required to process the flag.
