-!- FUNCTION: Plays an inhibitory role on natural killer (NK) cells
cytotoxicity. Activation results in specific acid
sphingomyelinase/SMPD1 stimulation with subsequent marked elevation of
intracellular ceramide. Activation also leads to AKT1/PKB and
RPS6KA1/RSK1 kinases stimulation as well as markedly enhanced T-cell
proliferation induced by anti-CD3. Acts as a lectin that binds to the
terminal carbohydrate Gal-alpha(1,3)Gal epitope as well as to the N-
acetyllactosamine epitope. Binds also to CLEC2D/LLT1 as a ligand and
inhibits NK cell-mediated cytotoxicity as well as interferon-gamma
secretion in target cells. {ECO:0000269|PubMed:16455998,
