Anti-Human CD85j (ILT2) NALE(TM) Purified (Clone: HP-F1)

The HP-F1 monoclonal antibody reacts with human CD85j, a 110 kDa single transmembrane glycoprotein. The CD85 molecules encompass a large immunoregulatory family called Leuokocyte Immunoglobulin-like Receptors (LIRs) and Ig-Like Transcripts (ILTs). CD85j is also knows as Ig-like transcpript (ILT2) and leukocyte Ig-like receptor (LIR-1). It is expressed on subsets of NK, B and T cells and on myeloid cells such as monocytes and dendritic cells. CD85j is involved in viral infections. Protein function: Receptor for class I MHC antigens. Recognizes a broad spectrum of HLA-A, HLA-B, HLA-C and HLA-G alleles. Receptor for H301/UL18, a human cytomegalovirus class I MHC homolog. Ligand binding results in inhibitory signals and down-regulation of the immune response. Engagement of LILRB1 present on natural killer cells or T-cells by class I MHC molecules protects the target cells from lysis. Interaction with HLA-B or HLA-E leads to inhibition of the signal triggered by FCER1A and inhibits serotonin release. Inhibits FCGR1A-mediated phosphorylation of cellular proteins and mobilization of intracellular calcium ions. [The UniProt Consortium]
