The protein encoded by this gene is a transmembrane glycoprotein belonging to the immunoglobulin superfamily. The external domain mediates cell attachment to the extracellular matrix molecule vitronectin, while its intracellular domain interacts with the dynein light chain Tctex-1/DYNLT1. The gene is specific to the primate lineage, and serves as a cellular receptor for poliovirus in the first step of poliovirus replication. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]
GeneCards Summary for PVR Gene
PVR (Poliovirus Receptor) is a Protein Coding gene. Diseases associated with PVR include Poliomyelitis and Paralytic Poliomyelitis. Among its related pathways are Innate Immune System and T Cell Co-Signaling Pathway: Ligand-Receptor Interactions. Gene Ontology (GO) annotations related to this gene include receptor activity and virus receptor activity. An important paralog of this gene is NECTIN2.
UniProtKB/Swiss-Prot for PVR Gene
Mediates NK cell adhesion and triggers NK cell effector functions. Binds two different NK cell receptors: CD96 and CD226. These interactions accumulates at the cell-cell contact site, leading to the formation of a mature immunological synapse between NK cell and target cell. This may trigger adhesion and secretion of lytic granules and IFN-gamma and activate cytoxicity of activated NK cells. May also promote NK cell-target cell modular exchange, and PVR transfer to the NK cell. This transfer is more important in some tumor cells expressing a lot of PVR, and may trigger fratricide NK cell activation, providing tumors with a mechanism of immunoevasion. Plays a role in mediating tumor cell invasion and migration.
(Microbial infection) Acts as a receptor for poliovirus. May play a role in axonal transport of poliovirus, by targeting virion-PVR-containing endocytic vesicles to the microtubular network through interaction with DYNLT1. This interaction would drive the virus-containing vesicle to the axonal retrograde transport (PubMed:2538245). Acts as a receptor for pseudorabies virus (PubMed:9616127). Is prevented to reach cell surface upon infection by human cytomegalovirus /HHV-5, presumably to escape immune recognition of infected cell by NK cells (PubMed:15640804).
