Comments
SIGMAR1 is an integral membrane-bound protein found in various membranous compartments. It is widely expressed across the brain and functions as chaperone protein that regulates various signaling pathways. Miki et al. found that it accumulates in nuclear aggregates with p62 (NES entry #260) after treatment with leptomycin B. No putative NES has been identified yet. It is unclear whether it contains an NES itself or the change in localization is due to other effects through p62, which contains a putative NES.

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.
