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, ECO:0000269|PubMed:16925668, ECO:0000269|PubMed:8077657}. |Lectin C| |transmembrane signaling receptor activity| |carbohydrate binding| |regulation of immune response| |regulation of immune system process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp303|39°C R06 exp303]]|-2.06| |[[:results:exp29|Rapamycin 1μM R00 exp29]]|-1.76| |[[:results:exp416|Tubacin 1.6μM R07 exp416]]|1.7| |[[:results:exp121|Golgicide-A 2μM R03 exp121]]|1.92| No correlation found to any other genes in chemogenomics.
