Target Information

Integrins are heterodimeric integral membrane proteins composed of an alpha chain and a beta chain.
CD11b is implicated in various adhesive interactions of monocytes, macrophages and granulocytes as well as in mediating the uptake of complement coated particles. It is identical to CR3, the receptor for the iC3b fragment of the third complement component.
CD11b is also a receptor for fibrogen, factor X and ICAM1, and recognizes P1 and P2 peptides of fibrogen gamma chain.

The Mac1 CD11b antigen is present on macrophages, granulocytes, natural killer cells, and blood monocytes. CD11b is expressed on 8% spleen cells, 44% bone marrow cells, and less than 1% thymocytes, and is commonly used as a microglial marker in nervous tissue.

CD11c encodes the integrin alpha X chain protein, which combines with the beta 2 chain (ITGB2) to form a leukocyte-specific integrin referred to as inactivated-C3b (iC3b) receptor 4 (CR4). The alpha X beta 2 complex overlaps the properties of the alpha M beta 2 integrin in adherence of neutrophils and monocytes to stimulated endothelium cells, and in the phagocytosis of complement-coated particles.
Mutations affecting the CD11b/c gene lead to systemic lupus erythematosus 6.
