General description

Leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is a transmembrane glycoprotein which is a part of the leukocyte receptor complex (LRC)-encoded family. In its cytoplasmic domain, it contains two immunoreceptor tyrosine-based inhibition motifs (ITIMs). It is widely expressed on immune cells such as B cells, T cells, natural killer (NK) cells, monocytes, dendritic cells and CD34+ hematopoietic progenitor cells. LAIR-1 gene maps to human chromosome 19q13.4, and codes for a type I transmembrane protein, consisting of 287 amino acids. It has one C2-type Ig-like domain in its exoplasmic region. This gene contains 10 exons, and alternative splicing gives rise to many isosforms such as, LAIR-1a, LAIR-1b, LAIR-1c and LAIR-1d.

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

Leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) suppresses the cytotoxic activity of natural killer (NK) cells, and also inhibits the differentiation of blood precursor cells into dendritic cells. It interacts with CD3 and prevents the cytotoxicity of effector T-cells. It cross links with B-cells, and prevents B-cell receptor (BCR)-induced calcium mobilization, as well as inhibition of immunoglobulin (Ig) and cytokine production. It inhibits protein kinase B (PKB) activation and granulocyte-macrophage colony-stimulating factor (GM-CSF)-dependent proliferation of leukemia cells. It might be involved in the regulation of immune response by extracellular matrix (ECM), by interacting with collagen, which leads to suppression of immune response. In rheumatoid arthritis (RA) patients, LAIR-1 is expressed on macrophages of inflamed synovial tissue. It prevents osteoclastogenesis, which might be useful for designing therapy for RA. It is also involved in the proliferation and invasion of epithelial ovarian cancer cells.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Leukocyte-associated immunoglobulin-like receptor-1 is an inhibitory receptor primarily expressed by immune cells. This study was undertaken to define the role of this molecule in osteoclast differentiation and rheumatoid arthritis. In vitro osteoclast assays were performed to characterize the role of

C1q collagen-like region (CLR) engaging and activating the LAIR-1 inhibitory immunoreceptor represents a non-complement mechanism for maintaining immune quiescence. Given the binding promiscuity of C1q's globular region (gC1q), we hypothesized that C1q concurrently associates with distinct inhibitory immunoreceptors to produce
