U-Blot® Recombinant CD326 (VF0018) Fc-Fused Nanobody

Background：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.
