Comments
hPER1 functions as the transcriptional repressor in the circadian clock. Mouse homolog is listed in entry 30. Two putative NESs were identified by in silico prediction methods in Sendino et al. using possible XPO1/CRM1-cancer exportome proteins identified previously as putative CRM1-binders by Kirli et al. (not all proteins were validated in full-length). One of the NES is homologous to the one found in mPER1 and was tested using Rev(1.4)-GFP and SRVB/A reporters based on replacing survivin NES and with other peptide sequences. CRM1-dependency is illustrated by cytoplasmic accumulation of the reporter when co-expressed with CRM1. Another putative NES is found in 1215-1233 but the export activity of this isolated NES is weak and did not respond to CRM1 co-expression.

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.
