Biotinylated Human LILRB2/CD85d/ILT4 Protein 4781

Additional Information:
express systemHEK293|product tagC-His-Avi|purity> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC|backgroundThe immunoglobulin-like transcript (ILT) comprise a family of activating and inhibitory type immunoreceptors whose genes are located in the same locus that encodes killer cell Ig-like receptors (KIR). ILT4, also known as LIR-2 and LILRB2, is a type I transmembrane protein expressed primarily on monocytes and dendritic cells (DC). LILRB2 is a receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C, HLA-G and HLA-F alleles.|molecular weightThe protein has a predicted MW of 50.2 kDa. Due to glycosylation, the protein migrates to 70-75 kDa based on Tris-Bis PAGE result.|available size100 g, 500 g|endotoxinLess than 1EU per g by the LAL method.|Biotinylated Human LILRB2/CD85d/ILT4 Protein 4781proteinSize and concentration100, 500g and lyophilizedFormLyophilizedStorage InstructionsValid for 12 months from date of receipt when stored at -80C.

Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C, HLA-G and HLA-F alleles.Protein namesLeukocyte immunoglobulin-like receptor subfamily B member 2 (LIR-2) (Leukocyte immunoglobulin-like receptor 2) (CD85 antigen-like family member D) (Immunoglobulin-like transcript 4) (ILT-4) (Monocyte/macrophage immunoglobulin-like receptor 10) (MIR-10) (CD antigen CD85d)Gene namesLILRB2,LILRB2 ILT4 LIR2 MIR10Mass9606DaFunctionReceptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C, HLA-G and HLA-F alleles (PubMed:11169396, PubMed:12853576, PubMed:16455647, PubMed:20448110, PubMed:27859042). Involved in the down-regulation of the immune response and the development of tolerance. Recognizes HLA-G in complex with B2M/beta-2 microglobulin and a nonamer self-peptide (peptide-bound HLA-G-B2M) triggering differentiation of type 1 regulatory T cells and myeloid-derived suppressor cells, both of which actively maintain maternal-fetal tolerance (PubMed:16455647, PubMed:20448110, PubMed:27859042). Competes with CD8A for binding to class I MHC antigens. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions (PubMed:11875462, PubMed:12853576, PubMed:9548455, PubMed:9842885).Subellular locationCell membrane ; Single-pass type I membrane protein.TissuesExpressed in monocytes and at lower levels in myeloid and plasmacytoid dendritic cells. Expressed in tolerogenic IL10-producing dendritic cells (PubMed:20448110). Expressed in myeloid-derived suppressor cells during pregnancy (PubMed:27859042). Detected at low levels in natural killer (NK) cells. Expressed in B cells.StructureBinds PTPN6 when phosphorylated. Binds FCGR1A. Interacts with peptide-bound HLA-G-B2M; this interaction is direct (PubMed:16455647). Interacts with peptide-bound HLA-F-B2M; this interaction is direct (PubMed:11169396).Post-translational modificationPhosphorylated on tyrosine residues. Dephosphorylated by PTPN6.DomainCoTarget Relevance information above includes information from UniProt accession: Q8N423The UniProt Consortium|
