- Biotinylated Human LILRB1 / CD85j / ILT2 Protein, Fc Tag, Avi Tag (Avitag)
- Fc gamma RIIIB / CD16b (NA1)
|Synonyms||Fc gamma RIIIB / CD16b (NA1),FCGR3B,CD16B,FCG3B,FCGR3,FCG3,IGFR3|
|Characteristics||This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag). The protein has a calculated MW of 75.6 kDa. As a result of glycosylation, the protein migrates as 100-116 kDa under reducing (R) condition, and 150 kDa under non|
|Endotoxin Level||Less than 1.0 EU per μg by the LAL method.|
|Purity||>95% as determined by SDS-PAGE.|
|Description||CD85 antigen-like family member J (CD85J) is also known as Leukocyte immunoglobulin-like receptor subfamily B member 1 (LILRB1 or LIR-1), Immunoglobulin-like transcript 2 (ILT-2), Monocyte/macrophage immunoglobulin-like receptor 7 (MIR7), which belongs to leukocyte immunoglobulin-like receptor (LIR) family. CD85J / LILRB1 Contains 4 Ig-like C2-type (immunoglobulin-like) domains. CD85J / LIR-1 is expressed predominantly on B-cells and monocytes. CD85J is receptor for class I MHC antigens and recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles and is also receptor for H301/UL18, a human cytomegalovirus class I MHC homolog. Ligand binding results in inhibitory signals and down-regulation of the immune response. CD85J / LILRB1 interaction with HLA-B or HLA-E leads to inhibition of the signal triggered by FCER1A and inhibits serotonin release. CD85J / LILRB1 inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions.|
