CoV-UniBind - Coronavirus Unified Binding Database

CoV-UniBind curates and integrates structural and biochemical data on antibodies specifically elicited by SARS-CoV-2 and related coronaviruses. It links 3D antibody structures to their binding properties across viral variants, incorporating epitope and sequence information. This dataset serves as a comprehensive resource for analysing antibody-antigen interactions in the context of COVID-19 and provides a foundation for binding classification and regression tasks using deep learning models.
