In this study, we explore the structural bases of receptor binding and immune evasion for the Omicron BA.2.86, JN.1, EG.5, EG.5.1, and HV.1 sub-variants. Our findings reveal that BA.2.86 exhibits strong receptor binding, whereas its JN.1 sub-lineage displays a decreased binding affinity to human ACE2 (hACE2). Through complex structure analyses, we observed that the reversion of R493Q in BA.2.86 receptor binding domain (RBD) plays a facilitating role in receptor binding, while the L455S substitution in JN.1 RBD restores optimal affinity. Furthermore, the structure of monoclonal antibody (mAb) S309 complexed with BA.2.86 RBD highlights the importance of the K356T mutation, which brings a new N-glycosylation motif, altering the binding pattern of mAbs belonging to RBD-5 represented by S309. These findings emphasize the importance of closely monitoring BA.2.86 and its sub-lineages to prevent another wave of SARS-CoV-2 infections. | |||||||||
