(integrin alphaM subunit) is a 165-170 kDa type I transmembrane glycoprotein that non-covalently associates with integrin beta2 subunit (CD18); expression of the CD11b chain on the cell surface requires the presence of the CD18 antigen. CD11b/CD18 integrin (Mac-1, CR3) is highly expressed on NK cells, neutrophils, monocytes and less on macrophages.
CD11b/CD18 integrin is implicated in various adhesive interactions of monocytes, macrophages and granulocytes, facilitating their diapedesis, as well as it mediates the uptake of complement coated particles, serving as a receptor for the iC3b fragment of the third complement component.
The antibody MEM-170 recognizes CD11b antigen (Mac-1alpha), a 165-170 kDa transmembrane protein type 1 mainly expressed on monocytes, granulocytes and NK-cells. The antibody blocks (not completely) Mac-1-mediated neutrophil binding to fibrinogen.
