|Function||Coreceptor for bacterial lipopolysaccharide (PubMed:1698311, PubMed:23264655). In concert with LBP, binds to monomeric lipopolysaccharide and delivers it to the LY96/TLR4 complex, thereby mediating the innate immune response to bacterial lipopolysaccharide (LPS) (PubMed:20133493, PubMed:23264655). Acts via MyD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response (PubMed:8612135). Acts as a coreceptor for TLR2:TLR6 heterodimer in response to diacylated lipopeptides and for TLR2:TLR1 heterodimer in response to triacylated lipopeptides, these clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway (PubMed:16880211). Binds electronegative LDL (LDL(-)) and mediates the cytokine release induced by LDL(-) (PubMed:23880187).|
|Cellular Location||Cell membrane; Lipid- anchor, GPI-anchor. Secreted Membrane raft. Golgi apparatus. Note=Secreted forms may arise by cleavage of the GPI anchor.|
|Tissue Location||Detected on macrophages (at protein level) (PubMed:1698311). Expressed strongly on the surface of monocytes and weakly on the surface of granulocytes; also expressed by most tissue macrophages.|

CD14 is a glycophosphatidylinositol-anchored protein expressed on the surfaces of monocytes and plymorphonuclear leukocytes. It acts as a co-receptor for the detection of bacterial lipopolysaccharide (LPS) (1). CD14 cooperates with MD-2 and TLR4 to mediate the innate immune response to bacterial LPS. It acts via MyD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response (2). CD14 is expressed strongly on peripheral blood monocytes and macrophages, and weakly on the surface of granulocytes (1).
