CD2 and infection: The protein pEP402R, a homologue of the T-lymphocyte surface antigen CD2, encoded by the EP402R gene is located in the lipoprotein membrane of the outer viral envelope and plays an important role in the adhesion of erythrocytes to infected cells (hemadsorption) and the binding of the ASFV particles to host erythrocytes during infection (Alejo et al. 2018; Dixon et al. 2019).
