Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Binds bacterial lipopolysaccharide (LPS) (PubMed:17569869, PubMed:17803912). Cooperates with TLR4 in the innate immune response to bacterial lipopolysaccharide (LPS), and with TLR2 in the response to cell wall components from Gram-positive and Gram-negative bacteria (PubMed:11160242, PubMed:11593030). Enhances TLR4-dependent activation of NF-kappa-B (PubMed:10359581). Cells expressing both LY96 and TLR4, but not TLR4 alone, respond to LPS (PubMed:10359581).SUBUNIT Heterogeneous homomer formed from homodimers; disulfide-linked (PubMed:11593030, PubMed:12642668). Belongs to the lipopolysaccharide (LPS) receptor, a multi-protein complex containing at least CD14, LY96 and TLR4 (PubMed:11274165). Binds to the extracellular domains of TLR2 and TLR4 (PubMed:10359581, PubMed:11593030, PubMed:17803912). Ligand binding induces interaction with TLR4 and oligomerization of the complex.SUBCELLULAR LOCATION Retained in the extracellular space at the cell surface by interaction with TLR4 (PubMed:10359581).ALTERNATIVE PRODUCTS N-glycosylated; high-mannose.
