anti-LAIR1 (human), Rabbit Monoclonal (RM498)

Product description: Recombinant Antibody. This antibody reacts to human LAIR1. Isotype: Rabbit IgG. Immunogen: Recombinant extracellular domain of human LAIR1. Application: IHC, WB. Liquid. 50% Glycerol/PBS with 1% BSA and 0.09% sodium azide. LAIR1 functions as an inhibitory receptor that plays a constitutive negative regulatory role on the cytolytic function of natural killer (NK) cells, B-cells and T-cells. Activation by Tyr phosphorylation results in the recruitment and activation of the phosphatases PTPN6 and PTPN11. It also reduces the increase of intracellular calcium evoked by B-cell receptor ligation. May also play its inhibitory role independently of SH2-containing phosphatases. Modulates cytokine production in CD4+ T-cells, down-regulating IL2 and IFNG production while inducing secretion of transforming growth factor beta. Down-regulates IgG and IgE production in B-cells as well as IL8, IL10 and TNF secretion. Inhibits proliferation and induces apoptosis in myeloid leukemia cell lines as well as prevents nuclear translocation of NF-kappa-B p65 subunit/RELA and phosphorylation of I-kappa-B alpha/CHUK in these cells. Inhibits the differentiation of peripheral blood precursors towards dendritic cells. LAIR1 plays a role in immune response homeostasis, and extracellular matrix remodeling and it is overexpressed in many high-grade cancers.
