Viral core import involves translocating the HIV-1 capsid at the nuclear pore complex (NPC). Notably, the central channel of the NPC appears to often accommodate and allow passage of intact HIV-1 capsid, though mechanistic details of the process remain to be fully understood. Here, we investigate the molecular interactions that operate in concert between the HIV-1 capsid and the NPC that regulate capsid translocation through the central channel. To this end, we develop a \u201cbottom-up\u201d coarse-grained (CG) model of the human NPC from recently released cryo-electron tomography structure and then construct composite membrane-embedded CG NPC models. We find that successful translocation from the cytoplasmic side to the NPC central channel is contingent on the compatibility of the capsid morphology and channel dimension and the proper orientation of the capsid approach to the channel from the cytoplasmic side. The translocation dynamics is driven by maximizing the contacts between phenylalanine-glycine nucleoporins at the central channel and the capsid. For the docked intact capsids, structural analysis reveals correlated striated patterns of lattice disorder likely related to the intrinsic capsid elasticity. Uncondensed genomic material inside the docked capsid augments the overall lattice disorder of the capsid. Our results suggest that the intrinsic \u201celasticity\u201d can also aid the capsid to adapt to the stress and remain structurally intact during translocation.<\/jats:p>","DOI":"10.1073\/pnas.2313737121","type":"journal-article","created":{"date-parts":[[2024,1,19]],"date-time":"2024-01-19T14:06:31Z","timestamp":1705673191000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":55,"title":["HIV-1 capsid shape, orientation, and entropic elasticity regulate translocation into the nuclear pore complex"],"prefix":"10.1073","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4279-4000","authenticated-orcid":false,"given":"Arpa","family":"Hudait","sequence":"first","affiliation":[{"name":"Department of Chemistry, Chicago Center for Theoretical Chemistry, Institute for Biophysical Dynamics, and James Franck Institute, The University of Chicago, Chicago, IL 60637"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3267-6748","authenticated-orcid":false,"given":"Gregory A.","family":"Voth","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Chicago Center for Theoretical Chemistry, Institute for Biophysical Dynamics, and James Franck Institute, The University of Chicago, Chicago, IL 60637"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2024,1,19]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrmicro.2016.162"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature12769"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.74.3.1168-1177.2000"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/nsmb785"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/35030177"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.283.5398.80"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.add7434"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.aah4972"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1093\/emboj\/cdg143"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature15381"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12985-020-01301-5"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.00476-15"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.01024-19"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chom.2018.03.009"},{"key":"e_1_3_4_15_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1706245114"},{"key":"e_1_3_4_16_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.2019467118"},{"key":"e_1_3_4_17_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1920631117"},{"key":"e_1_3_4_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2021.01.025"},{"key":"e_1_3_4_19_2","doi-asserted-by":"publisher","DOI":"10.7554\/eLife.64776"},{"key":"e_1_3_4_20_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.abb4808"},{"key":"e_1_3_4_21_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-020-2443-1"},{"key":"e_1_3_4_22_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.abm9506"},{"key":"e_1_3_4_23_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.abm9129"},{"key":"e_1_3_4_24_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.abm9798"},{"key":"e_1_3_4_25_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41564-020-0735-8"},{"key":"e_1_3_4_26_2","doi-asserted-by":"publisher","DOI":"10.1186\/1742-4690-10-81"},{"key":"e_1_3_4_27_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.00325-11"},{"key":"e_1_3_4_28_2","doi-asserted-by":"publisher","DOI":"10.1021\/acs.jctc.2c00643"},{"key":"e_1_3_4_29_2","doi-asserted-by":"publisher","DOI":"10.1038\/ncomms11568"},{"key":"e_1_3_4_30_2","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.9b01413"},{"key":"e_1_3_4_31_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-020-15106-1"},{"key":"e_1_3_4_32_2","doi-asserted-by":"publisher","DOI":"10.1021\/jacs.2c02568"},{"key":"e_1_3_4_33_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1706600114"},{"key":"e_1_3_4_34_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-022-28654-5"},{"key":"e_1_3_4_35_2","doi-asserted-by":"publisher","DOI":"10.1529\/biophysj.108.139626"},{"key":"e_1_3_4_36_2","doi-asserted-by":"publisher","DOI":"10.1529\/biophysj.108.139733"},{"key":"e_1_3_4_37_2","doi-asserted-by":"publisher","DOI":"10.1063\/1.2992060"},{"key":"e_1_3_4_38_2","article-title":"Efficient Simulation of Tunable Lipid Assemblies Across Scales and Resolutions","author":"Grime J.
