靶點詳情

  • 功能：
    Functions as an inhibitory receptor that plays a constitutive negative regulatory role on cytolytic function of natural killer (NK) cells, B-cells and T-cells. Activation by Tyr phosphorylation results in 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 also 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.

    1. These findings demonstrate that C1q and it's globular region interact with CD33 to activate its inhibitory motifs, while the collagen-like region does not. Whole C1q is required to crosslink CD33 and LAIR-1 and concurrently activate CD33/LAIR-1 inhibitory motifs. PMID: 28325905

    32. both constitutive and sIgM-induced phosphorylation of p38 and JNK is inhibited by LAIR-1 through an ITIM-dependent signal; this inhibitory signal is missing when LAIR-1 is not expressed as occurs in HR CLL. PMID: 18288129
    33. Human collagen II peptides II-17, -30 and -56 and collagen III peptides III-1, -30, -38, -44, -45, and -51 specifically interacted with hLAIR-1 expressed on K562 cells. PMID: 19345263
