Function

FUNCTION: Adapter protein that plays a key role in innate immune response to a number of intracellular pathogens, such as C.albicans and L.monocytogenes. Is at the crossroads of ITAM- tyrosine kinase and the Toll-like receptors (TLR) and NOD2 signaling pathways. Probably controls various innate immune response pathways depending on the intracellular pathogen. In response to L.monocytogenes infection, acts by connecting NOD2 recognition of peptidoglycan to downstream activation of MAP kinases (MAPK) without activating NF-kappa-B. Also involved in activation of myeloid cells via classical ITAM-associated receptors and TLR: required for TLR-mediated activation of MAPK, while it is not required for TLR-induced activation of NF-kappa-B (By similarity). Controls CLEC7A (dectin-1)-mediated myeloid cell activation induced by the yeast cell wall component zymosan, leading to cytokine production and innate anti-fungal immunity: acts by regulating BCL10-MALT1-mediated NF-kappa-B activation pathway. Activates NF-kappa-B via BCL10. In response to the hyphal form of C.albicans, mediates CLEC6A (dectin-2)-induced I-kappa-B kinase ubiquitination, leading to NF-kappa-B activation via interaction with BCL10. In response to fungal infection, may be required for the development and subsequent differentiation of interleukin 17-producing T helper (TH-17) cells. {ECO:0000250, ECO:0000269|PubMed:11053425}.;

Disease

DISEASE: Candidiasis, familial, 2 (CANDF2) [MIM:212050]: A primary immunodeficiency disorder with altered immune responses and impaired clearance of fungal infections, selective against Candida. It is characterized by persistent and/or recurrent infections of the skin, nails and mucous membranes caused by organisms of the genus Candida, mainly Candida albicans. {ECO:0000269|PubMed:19864672, ECO:0000269|PubMed:23335372, ECO:0000269|PubMed:24131138}. Note=The disease is caused by mutations affecting the gene represented in this entry. Defects induce reduced numbers of CD4(+) Th17 lymphocytes as well as a lack of monocyte-derived cytokines in response to Candida strains. Neutrophils show a selective Candida albicans killing defect with abnormal ultrastructural phagolysosomes and outgrowth of hyphae (PubMed:23335372). {ECO:0000269|PubMed:23335372}.;
