Comments
Bovine herpesvirus type-1 (BHV-1)infected cell protein 27 (BICP27) is a nucleolar protein and has both a nuclear localizaiton signal as well as a nucleolar localization signals. An early protein with postranscriptional roles, BICP27 has been shown to partake in continuous nucleo-cytoplasmic shuttling. The shuttling activities of some viral proteins depend on virus-encoded cofacts, but BICP27 shuttling occurs in the absence of a viral infection. All single-leucine mutations lost shuttling activity, therefore indicating that each one is critical for export.

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.
