Description

This recombinant monoclonal antibody is designed as a research-grade biosimilar to TGI-2, targeting PVRIG (PVR-related immunoglobulin domain-containing protein), also known as CD112R. PVRIG functions as an inhibitory immune checkpoint receptor expressed on T cells and NK cells that binds to its ligand PVRL2 (CD112), delivering negative signals that suppress immune cell activation and cytotoxic function. This checkpoint pathway represents an important mechanism by which tumors evade immune surveillance, as PVRL2 is frequently upregulated on various cancer cells. PVRIG co-expression with other checkpoint receptors like PD-1 and TIGIT has been observed in tumor-infiltrating lymphocytes, contributing to T cell exhaustion in the tumor microenvironment.

TGI-2 is a reference antibody used in preclinical research investigating PVRIG blockade as a cancer immunotherapy strategy. This biosimilar antibody serves as a valuable research tool for studying PVRIG-mediated immune regulation, evaluating combination checkpoint blockade approaches, and exploring mechanisms of tumor immune evasion. It enables investigators to assess the therapeutic potential of targeting the PVRIG/PVRL2 axis in oncology and immunology research.

Usage

It is a non-therapeutic biosimilar antibody, owning the same variable region from the corresponding approved therapeutic antibody. In conclusion, it is a research-grade biosimilar antibody and expressed in mammalian cell, which can be directly used as positive controls in drug discovery or used for rapid verification of the biological functions of target protein.

Target Background

Function

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.

Gene References into Functions

Blockade of TIGIT or CD112R, separately or together, enhances trastuzumab-triggered antitumor response by human NK cells. PMID: 28623459
Describe CD112R, a member of poliovirus receptor-like proteins, as a new coinhibitory receptor for T cells. CD112R is preferentially expressed on T cells and inhibits T cell receptor-mediated signals. PMID: 26755705

Subcellular Location

Cell membrane; Multi-pass membrane protein.

Tissue Specificity

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-
