[5] It is a membrane protein with three extracellular immunoglobulin domains, a single transmembrane helix and a cytoplasmic tail.

PVRL1 is an adhesion molecule found in a wide range of tissues where it localizes in various junctions such as the adherens junction of epithelial tissue or the chemical synapse of neurons.

The protein has been revealed as one of the key players in mediating cellular entry of the Herpes simplex virus by interacting with the viral glycoprotein D (gD).
