Description
- Anti-CD11b/CD18, clone mAb107, Cat
- No
- MABF2085, is a mouse monoclonal antibody that detects CD11b/CD18 nd has been tested for use in Dot Blot, Flow Cytometry, Immunohistochemistry, and Inhibition assay
- Integrin alpha-M (UniProt: P11215; also known as CD11 antigen-like family member B, CR-3 alpha chain, Cell surface glycoprotein MAC-1 subunit alpha, Leukocyte adhesion receptor MO1, Neutrophil adherence receptor, CD11b) is encoded by the ITGAM (also known as CD11B, CR3A) gene (Gene ID: 3684) in human
- Integrins are alpha/beta heterodimeric adhesion receptors that couple the extracellular matrix on other cells with the contractile cytoskeleton to transduce mechanochemical signals across the plasma membrane
- CD11b is a single-pass type I membrane protein that is synthesized with a signal peptide (aa 1-16), which is cleaved off in the mature form
- It is predominantly expressed in monocytes and granulocytes and some expression is also observed in neutrophils
- It is usually found as a heterodimer of alpha and beta subunits and associates with Integrin beta-2 (ITGB2)
- Two isoforms of CD11b have been reported that are produced by alternative splicing
- CD11b contains a large extracellular domain (aa 17-1104), a short transmembrane domain (aa 1105-1128), and a cytoplasmic domain (aa 1129-1152)
- It has been implicated in various adhesive interactions of monocytes, macrophages and granulocytes as well as in mediating the uptake of complement-coated particles
- It contains a metal ion-dependent adhesion site (MIDAS) in the integrin A domain, which is essential for stabilization of domain A in high affinity state
- The major ligand recognition site of CD11b/CD18 has been mapped to the A-domain in the CD11b subunit (CD11bA)
- Both magnesium and calcium ions exhibit equal affinities for the inactive CD11bA, however, upon activation there is a 10-fold increase in the binding affinity of magnesium ions without affecting affinity of calcium ions
- Mutations in ITGAM gene are known to cause Systemic lupus erythematosus 6, which is characterized by wide range of system dysfunctions, principally involving skin, joints, kidneys and serosal membranes
