Background of the antigen
Promotes cell-cell contacts by forming homophilic or heterophilic trans-dimers. Heterophilic interactions have been detected between PVRL1/nectin-1 and PVRL3/nectin-3 and between PVRL1/nectin-1 and PVRL4/nectin-4. Functions as an entry receptor for herpes simplex virus and pseudorabies virus. Has some neurite outgrowth-promoting activity.
