The NKp44/NCR2 protein is a cytotoxicity-activating receptor on natural killer (NK) cells that may increase their tumor cell lysis efficiency. NKp44/NCR2 interacts with TYROBP/DAP12, an important signal transduction adapter, and is critical for transducing signals that activate NK cells against target cells. NKp44/NCR2 Protein, Human (HEK293, His) is the recombinant human-derived NKp44/NCR2 protein, expressed by HEK293 , with C-6*His labeled tag.
