Summary

PVR (PVR cell adhesion molecule, HGNC:9705) is a protein-coding gene on chromosome 19q13.31, encoding Poliovirus receptor (P15151). Mediates NK cell adhesion and triggers NK cell effector functions.

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.

Function. 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 cytotoxicity 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. (Microbial infection) Acts as a receptor for Pseudorabies virus. (Microbial infection) Is prevented to reach cell surface upon infection by Human cytomegalovirus /HHV-5, presumably to escape immune recognition of infected cell by NK cells.

Subunit / interactions. Can form trans-heterodimers with NECTIN3. The extracellular domain interacts with VTN, CD226 and CD96. The cytoplasmic domain interacts with DYNLT1. Binds with high affinity to TIGIT. (Microbial infection) Interacts with poliovirus capsid proteins. (Microbial infection) Interacts with human cytomegalovirus /HHV-5 UL141 protein. (Microbial infection) Interacts with pseudorabies virus gD protein.

Subcellular location. Cell membrane Cell membrane Secreted Secreted.

Post-translational modifications. N-glycosylated. N-glycan at Asn-120: Hex5HexNAc4. Phosphorylated by Src kinases on tyrosine residues in the ITIM motif upon ligation. Interaction with TIGIT is required for Phosphorylation.

Domain organisation. Contains 1 copy of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). The phosphorylated ITIM motif can bind the SH2 domain of several SH2-containing phosphatases.

Induction. Transcriptionally regulated by SHH.

Miscellaneous. The V-type domain is necessary and sufficient for virus binding and uptake.

Similarity. Belongs to the nectin family.
