NKG2A/CD159a
NKG2A (CD159a), encoded by KLRC1, is an inhibitory C-type lectin receptor that forms obligate heterodimers with CD94 on NK cells and CD8 T cells. The CD94/NKG2A complex recognizes the non-classical MHC class I molecule HLA-E presenting signal peptides derived from classical HLA leaders, and the cytoplasmic ITIM of NKG2A delivers inhibitory signals via SHP phosphatases, protecting healthy HLA-E-expressing cells from NK attack. Elevated NKG2A expression on tumor-infiltrating NK and CD8 T cells is associated with impaired antitumor immunity, and the blocking antibody monalizumab is in clinical development, including combinations with EGFR-directed therapy in head and neck cancer.

The EpCAM/TROP1 protein serves as an important homogeneous interacting molecule that promotes direct contact between intestinal epithelial cells (IEC) and intraepithelial lymphocytes (IEL) in the mucosal epithelium. This feature helps establish an immune barrier against mucosal infections. EpCAM/TROP1 Protein, Human (His-SUMO) is the recombinant human-derived EpCAM/TROP1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.
