BM1 has shown to harbor two leucine-rich CRM1-dependent nuclear export signals (3-14aa and 124-133aa) and one bipartite nuclear localization signal (NLS) (76-94aa), The distribution of NES1-mutant L12/14A showed no difference from the wild type BM1. NES2-mutant M131A/L133A was distributed evenly between the cytoplasm and nucleus of most of transfected cells while the NES1/2-mutant M131A/L133/12/14A was predominantly distributed in the nucleus of most of the transfected cells.

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.
