Function [CC]:
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). {ECO:0000269|PubMed:16880211, ECO:0000269|PubMed:1698311, ECO:0000269|PubMed:20133493, ECO:0000269|PubMed:23264655, ECO:0000269|PubMed:23880187, ECO:0000269|PubMed:8612135}.
Analysis Summary:
Chain (2); Disulfide bond (4); Glycosylation (5); Lipidation (1); Natural variant (2); Propeptide (1); Region (1); Repeat (11); Sequence conflict (2); Signal peptide (1); The expression in monocytes is highly induced by 27-hydroxycholesterol, priming monocytes/macrophages such that LPS-mediated inflammatory reaction is accelerated. Secretion of soluble CD14 is also enhanced. {ECO:0000269|PubMed:25497142}.; 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. {ECO:0000269|PubMed:1698311, ECO:0000269|PubMed:25497142}.
