Basigin does not facilitate SARS-CoV-2 entry, say researchers

Researchers investigated the significance of a transmembrane glycoprotein basigin, or CD147, as a host cell co-receptor required for the entry of SARS-CoV-2. The findings reveal that recombinant human basigin does not interact with full-length spike protein or spike RBD of SARS-CoV-2.
