Rev has a nuclear localization signal (NLS; AA 35-50) with an arginine-rich motif (ARM) that interacts with importin beta and a leucine-rich nuclear export signal (NES; AA 75-84) recognized by CRM1/exportin 1. Here we explore nuclear targeting activities of the transport signals of Rev. GFP tagging and quantitative fluorescence microscopy were used to study the localization behavior of Rev NLS/ARM mutants under conditions inhibiting the export of Rev. Rev mutant M5 was actively transported to the nucleus, despite its known failure to bind importin beta. Microinjection of transport substrates with Rev-NES peptides revealed that the Rev-NES has both nuclear import and export activities. Replacement of amino acid residues \"PLER\" (77-80) of the NES with alanines abolished bidirectional transport activity of the Rev-NES. These results indicate that both transport signals of Rev have nuclear import capabilities and that the Rev NLS has more than one nuclear targeting activity. This suggests that Rev is able to use various routes for nuclear entry rather than depending on a single pathway.","is_dataset_classified":null,"base_score":2.639057329615259,"endowment":2.639057329615259,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"14644169","pmcid":null,"openalex_id":"https://openalex.org/W2016587446","authors":[],"funders":[],"total_grants":0,"fwci":0.5701,"citation_percentile":0.63656026,"influential_citations":0,"citation_trend":[{"year":2017,"count":1},{"year":2018,"count":1},{"year":2019,"count":1}],"oa_status":"green","license":"cc-by-nc-nd","oa_locations":[{"url":"http://hdl.handle.net/2108/52222","host_type":"repository"},{"url":"http://hdl.handle.net/2108/52222","host_type":"repository"},{"url":"https://api.elsevier.com/content/article/PII:S0014482703004154?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0014482703004154?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.yexcr.2003.07.011","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/14644169","host_type":"repository"},{"url":"https://mediatum.ub.tum.de/1334912","host_type":"repository"},{"url":"https://push-zb.helmholtz-muenchen.de/frontdoor.php?source_opus=10181","host_type":"repository"},{"url":"https://publications.rwth-aachen.de/record/148296","host_type":"repository"}],"fields_of_study":["Nuclear Structure and Function","RNA Research and Splicing","RNA regulation and disease","Active Transport, Cell Nucleus","Amino Acid Motifs","Fatty Acids, Unsaturated","Gene Products, rev","Green Fluorescent Proteins","HeLa Cells","Humans","Kinetics","Luminescent Proteins","Microscopy, Fluorescence","Mutation","Nuclear Localization Signals","Temperature","Transfection"],"mesh_terms":["Fatty Acids, Unsaturated","HeLa Cells","Humans","Kinetics","Luminescent Proteins","Microscopy, Fluorescence","Mutation","Temperature","Transfection","Gene Products, rev","Nuclear Localization Signals","Amino Acid Motifs","Active Transport, Cell Nucleus","Green Fluorescent Proteins","Hela Cells"],"keywords":["Biology","Human immunodeficiency virus (HIV)","Virology","Nuclear transport","Nuclear localization sequence","Cell biology","Virus","Computational biology","Cell nucleus","Nucleus"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Partnerships for the goals"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-27T02:29:48.405973Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
