CD161 protein plays a crucial role in inhibiting NK cell toxicity by activating specific acid sphingomyelinase/SMPD1 and increasing ceramide levels. Activation stimulates AKT1/PKB and RPS6KA1/RSK1 kinases, enhancing anti-CD3-induced T cell proliferation. CD161 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD161 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of CD161 Protein, Human (Biotinylated, HEK293, His-Avi) is 159 a.a., with molecular weight of 35-43 kDa.

Human

CD161 Protein assumes a crucial role in inhibiting natural killer (NK) cell cytotoxicity. Upon activation, CD161 stimulates specific acid sphingomyelinase/SMPD1, resulting in a significant increase in intracellular ceramide levels. The activation process also leads to the stimulation of AKT1/PKB and RPS6KA1/RSK1 kinases, along with a marked enhancement of T-cell proliferation induced by anti-CD3. Functioning as a lectin, CD161 binds to the terminal carbohydrate Gal-alpha(1,3)Gal epitope and the N-acetyllactosamine epitope. Furthermore, it acts as a ligand for CLEC2D/LLT1, inhibiting NK cell-mediated cytotoxicity and interferon-gamma secretion in target cells. Existing as a homodimer with disulfide linkage, CD161 interacts with acid sphingomyelinase/SMPD1, contributing to its multifaceted regulatory functions in immune responses.
