The PVRIG protein functions as a cell surface receptor for NECTIN2 and may serve as a co-inhibitory receptor capable of inhibiting T-cell receptor-mediated signaling. Upon interaction with NECTIN2, PVRIG inhibits T cell proliferation, suggesting its potential role in regulating immune responses. PVRIG Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived PVRIG protein, expressed by HEK293 , with C-6*His labeled tag.
