Comments
Phosphoprotein of HPIV2 was examined by Ohtsuka et al. A putative NES was identified by 1) deletion mutagenesis mapped an NES-containing region to 211-248, 2) looked for sequences that match consensus L/V/M/IxxxL/V/M/IxxL/V/M/IxL/V/M/I and found 225IIELLKGLDL234, 3) expressed as NLS-betaGal fusion and looked at localization +/- LMB, 4) made mutations in NES and saw decreased cytoplasmic localization. Mutation E227A/L228A only slightly decreased export, suggesting L288 side chain likely does not bind a hydrophobic pocket in the CRM1 groove.

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.
