CC -!- FUNCTION: Pathogen-recognition receptor expressed on the surface of
CC immature dendritic cells (DCs) and involved in initiation of primary
CC immune response. Thought to mediate the endocytosis of pathogens which
CC are subsequently degraded in lysosomal compartments. The receptor
CC returns to the cell membrane surface and the pathogen-derived antigens
CC are presented to resting T-cells via MHC class II proteins to initiate
CC the adaptive immune response. Probably recognizes in a calcium-
CC dependent manner high mannose N-linked oligosaccharides in a variety of
CC pathogen antigens (By similarity). {ECO:0000250}.
CC -!- FUNCTION: On DCs it is a high affinity receptor for ICAM2 and ICAM3 by
CC binding to mannose-like carbohydrates. May act as a DC rolling receptor
CC that mediates transendothelial migration of DC presursors from blood to
CC tissues by binding endothelial ICAM2. Seems to regulate DC-induced T-
CC cell proliferation by binding to ICAM3 on T-cells in the immunological
CC synapse formed between DC and T-cells (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homotetramer. Interacts with C1QBP; the interaction is
CC indicative for a C1q:C1QBP:CD209 signaling complex. Interacts with
CC ICAM2 and ICAM3 by binding to mannose-like carbohydrates. Interacts
CC (via C-type lectin domain) with CEACAM1 (via Lewis X moieties); this
CC interaction is regulated by the glycosylation pattern of CEACAM1 on
CC cell types and regulates contact between dendritic cells and
CC neutrophils. {ECO:0000250|UniProtKB:Q9NNX6}.
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250}; Single-pass type II
CC membrane protein {ECO:0000250}.
CC -!- DOMAIN: The tandem repeat domain, also called neck domain, mediates
CC oligomerization. {ECO:0000250}.
