CD112R gene encodes a single transmembrane protein consisting of a single extracellular IgV domain. Its long intracellular domain contains two tyrosine residues, one of which is within an ITIM-like motif. CD112R was initially named PVRIG for the homology observed between its second exon and the variable immunoglobulin domain of the polio virus receptor (PVR/CD155) and polio virus receptor-like (PVRL) genes. CD112R is a cell surface receptor for CD112/Nectin-2, it compete against CD226 in binding to CD112. Following interaction with CD112, CD112R inhibits T-cell proliferation and the disruption of interaction between CD112R and CD112 enhances T cell response. Published studies suggest that CD112R is a novel co-inhibitory receptor, or a checkpoint molecule, that suppressed TCR medicated signal.

Cell surface receptor for NECTIN2. May act as a coinhibitory receptor that suppresses T-cell receptor-mediated signals. Following interaction with NECTIN2, inhibits T-cell proliferation. Competes with CD226 for NECTIN2-binding.

Cell membrane ; Multi-pass membrane protein .

Expressed in some types of immune cells. Expressed at low levels on the surface of freshly isolated T-cells and natural killer (NK) cells, predominantly on CD8+ T-cells (mainly memory/effector, but not naive cells) and on both CD16+ and CD16- NK cells. T-cell expression levels are variable among individuals. Not detected in B-cells, naive or helper T-cells, monocytes, nor neutrophils (at protein level). Not detected in dendritic cells.
