NKG2A Protein, a crucial immune inhibitory receptor, forms a complex with KLRD1 on lymphocyte subsets for self-nonself discrimination. Recognizing HLA-E loaded with self-peptides, it monitors MHC class I expression in healthy cells, promoting self-tolerance. NKG2A transmits signals through ITIMs, recruiting tyrosine phosphatases to counteractivate receptors. As a key inhibitor on NK cells, it regulates their functions, distinguishing harmless from pathogenic antigens. In the tumor microenvironment, NKG2A acts as an immune inhibitory checkpoint, contributing to cell exhaustion. During viral infection, it inhibits NK cell cytotoxicity, facilitating viral immune escape. NKG2A-CD94 Heterodimer Protein, Mouse (HEK293, mFc) is a recombinant protein dimer complex containing mouse-derived NKG2A-CD94 Heterodimer protein, expressed by HEK293 , with C-mFc labeled tag. NKG2A-CD94 Heterodimer Protein, Mouse (HEK293, mFc), has molecular weight of 58-68 kDa.
