SaProtHub/ACE2_Omicron_XBB.1.5_binding_affinity

Base model: westlake-repl/SaProt_35M_AF2

Model Card for Model ID

This model is used to predict ACE2 binding affinities with mutant SARSCoV-2 Omicron XBB.1.5 variants spike receptor-binding domain (RBD).

Task type

protein level regression

Dataset description

The dataset is from Deep mutational scans of XBB.1.5 and BQ.1.1 reveal ongoing epistatic drift during SARSCoV-2 evolution.

Label means binding affinities level, ranging from minus infinity to positive infinity. Zero means no affinity, lager means higher affinity and smaller means lower affinity.
