|Other Names||Integrin alpha-M, 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, ITGAM, CD11B, CR3A|
|Target/Specificity||A synthetic peptide corresponding to C-terminus of human CD11b/ITAM protein was used as immunogen|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||CD11b/ITAM Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Integrin ITGAM/ITGB2 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 ITGAM/ITGB2 is also a receptor for fibrinogen, factor X and ICAM1. It recognizes P1 and P2 peptides of fibrinogen gamma chain. Regulates neutrophil migration (PubMed:28807980). In association with beta subunit ITGB2/CD18, required for CD177-PRTN3-mediated activation of TNF primed neutrophils (PubMed:21193407). May regulate phagocytosis-induced apoptosis in extravasated neutrophils (By similarity). May play a role in mast cell development (By similarity).|
|Cellular Location||Cell membrane; Single-pass type I membrane protein. Membrane raft; Single-pass type I membrane protein|
|Tissue Location||Predominantly expressed in monocytes and granulocytes (PubMed:1346576). Expressed in neutrophils (at protein level) (PubMed:21193407).|

Integrin alpha-M (ITAM, ITGAM, CD11b, MAC-1 alpha subunit, CR3 alpha chain) is the alpha subunit of ITAM/beta-2 complex (CD11b/CD18, Mac-1), a leukocyte adhesion heterodimeric glycoprotein (1). ITAM belongs to integrin alpha chain family and it is predominately presented in human myeloid cells, NK1 cells, monocytes, and granulocytes. ITAM/beta-2 complex is a receptor for fibrinogen (binding to P1 and P1 peptides of gamma chain), factor X, and ICAM1. ITAM/beta-2 is implicated in adhesive interactions of monocytes, macrophages, and granulocytes. It is also linked to mediation of complement-coated particle uptake (2).
