UniProtKB accession:  Q3KST4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Initiates virion attachment to host B-lymphocyte cell, leading to virus entry. Acts by binding to host CR2 at the surface of B-lymphocytes, facilitating the binding of viral glycoprotein gp42 to HLA class II molecules. Attachment triggers virion-host membrane fusion and invasion of the host cell (By similarity).
