Integrin alpha X chain protein is encoded by ITGAX gene. This protein 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 seems to overlap the properties of the alpha M beta 2 integrin in the adherence of neutrophils and monocytes to stimulated endothelium cells, and in the phagocytosis of complement coated particles. This protein has an extracellular domain of 1081 amino acids containing 10 potential glycosylation sites, a transmembrane domain of 26 amino acids, and a C-terminal cytoplasmic tail of 29 residues. It shows homology to the alpha subunits of platelet glycoprotein IIb/IIIa, vitronectin receptor, and fibronectin receptor. The receptors involved in both cell-cell and cell-matrix interactions appear to belong to a single superfamily of genes termed the integrins. It localizes in the 16p11.2 region of chromosome. The ITGAX has been reported in B-cell, Blood, Blood vessel, bone marrow, leucocyte, liver, spleen and uterus.
