Although such interactions can be modeled at different levels of coarse graining, in vitro experimental data have been quantitatively described by minimal models that describe FG Nups as cohesive homogeneous polymers and NTRs as uniformly cohesive spheres, in which the heterogeneous effects have been smeared out. By definition, these minimal models do not account for the explicit heterogeneities in FG Nup sequences, essentially a string of cohesive and noncohesive polymer units, and at the NTR surface. Here, we develop computational and analytical models that do take into account such heterogeneity in a minimal fashion and compare them with experimental data on single-molecule interactions between FG Nups and NTRs. Overall, we find that the heterogeneous nature of FG Nups and NTRs does play a role in determining equilibrium binding properties but is of much greater significance when it comes to unbinding and binding kinetics. Using our models, we predict how binding equilibria and kinetics depend on the distribution of cohesive blocks in the FG Nup sequences and of the binding pockets at the NTR surface, with multivalency playing a key role. Finally, we observe that single-molecule binding kinetics has a rather minor influence on the diffusion of NTRs in polymer melts consisting of FG-Nup-like sequences."}],"publication_status":"published","publication":"Biophysical Journal","_id":"10338","author":[{"last_name":"Davis","full_name":"Davis, Luke K.","first_name":"Luke K."},{"last_name":"Šarić","id":"bf63d406-f056-11eb-b41d-f263a6566d8b","first_name":"Anđela","full_name":"Šarić, Anđela","orcid":"0000-0002-7854-2139"},{"first_name":"Bart W.","full_name":"Hoogenboom, Bart W.","last_name":"Hoogenboom"},{"first_name":"Anton","full_name":"Zilman, Anton","last_name":"Zilman"}],"doi":"10.1016/j.bpj.2021.01.039","month":"02","date_created":"2021-11-25T15:36:36Z","citation":{"apa":"Davis, L.
