Comments
APRIL along with pp32 complex with HuR and CRM1 and contribute to CD83 mRNA export. CD83 mRNA is transported from the nucleus to the cytoplasm in a CRM1-dependent manner, and APRIL acts as an adapter molecule in that links HuR to CRM1. Phosphorylation of APRIL at Thr244A, close to the NLS, restricted APRIL to the cytoplasm. Nuclear export sequences were purported to be between amino acids 61-69, 85-93, and 110-118, although only mutation of the third NES prevented shuttling.
Doubts about NES: The proposed NES failed to bind CRM1 in GST-pulldown assay (Chook Lab, unpublished results).

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.
