Calcium-dependent lectin that acts as a pattern recognition receptor (PRR) of the innate immune system: specifically recognizes and binds alpha-mannans on C.albicans hypheas (PubMed:23911656, PubMed:28652405). Binding of C.albicans alpha-mannans to this receptor complex leads to phosphorylation of the immunoreceptor tyrosine-based activation motif (ITAM) of FCER1G, triggering activation of SYK, CARD9 and NF-kappa-B, consequently driving maturation of antigen-presenting cells and shaping antigen-specific priming of T-cells toward effector T-helper 1 and T-helper 17 cell subtypes (By similarity). Recognizes also, in a mannose-dependent manner, allergens from house dust mite and fungi, by promoting cysteinyl leukotriene production (By similarity). Recognizes soluble elements from the eggs of Shistosoma mansoni altering adaptive immune responses (By similarity). {ECO:0000250|UniProtKB:Q9JKF4, ECO:0000269|PubMed:23911656, ECO:0000269|PubMed:28652405}. This is the function of CLEC6A (C-type lectin domain containing 6A, Ensembl gene identifier ENSG00000205846).
