Glycoprotein 42

UniProtKB accession:  P03205

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays a role in virion attachment to host B-lymphocytes, through binding to leukocyte antigen (HLA) class II and subsequently participates in fusion of the virion with host membranes. May act as a tropism switch that directs fusion with B-lymphocytes and inhibits fusion with epithelial cells. Additionally, hampers T-cell recognition via HLA class II molecules through steric hindrance of T-cell receptor-class II-peptide interaction.
