ULBP1 Protein, Human (Biotinylated, HEK293, mFc-Avi)

The ULBP1/RAET1I protein is critical in the cytotoxicity of natural killer cells and can bind to and activate the KLRK1/NKG2D receptor. This mechanism highlights the importance of ULBP1/RAET1I in mediating cytotoxic responses. ULBP1 Protein, Human (Biotinylated, HEK293, mFc-Avi) is the recombinant human-derived ULBP1 protein, expressed by HEK293 , with C-Avi, C-mFc labeled tag.

The ULBP1/RAET1I protein plays a crucial role in natural killer cell cytotoxicity by acting as a ligand that binds to and activates the KLRK1/NKG2D receptor. This binding and activation mechanism highlights the significance of ULBP1/RAET1I in mediating the cytotoxic responses of natural killer cells. Moreover, it is noteworthy that ULBP1/RAET1I does not exhibit binding to beta2-microglobulin. This characteristic interaction profile underscores the specificity and selectivity of ULBP1/RAET1I in its engagement with KLRK1/NKG2D, emphasizing its pivotal role in immune responses and its potential as a therapeutic target for modulating natural killer cell activity.

Measured by its binding ability in a functional ELISA. Immobilized KLRK1 at 10 μg/mL can bind human Biotinylated ULBP1, the EC₅₀ is <8 ng/mL.
