ICC/IF Use at an assay dependent concentration.


  • FunctionIntegrin alpha-M/beta-2 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 with CR-3, the receptor for the iC3b fragment of the third complement component. It probably recognizes the R-G-D peptide in C3b. Integrin alpha-M/beta-2 is also a receptor for fibrinogen, factor X and ICAM1. It recognizes P1 and P2 peptides of fibrinogen gamma chain.
  • Tissue specificityPredominantly expressed in monocytes and granulocytes.
  • Involvement in diseaseSystemic lupus erythematosus 6
  • Sequence similaritiesBelongs to the integrin alpha chain family.
    Contains 7 FG-GAP repeats.
    Contains 1 VWFA domain.
  • DomainThe integrin I-domain (insert) is a VWFA domain. Integrins with I-domains do not undergo protease cleavage.
  • Cellular localizationMembrane.
