Integrin Alpha X
Definition 1
Leukocyte Surface Antigen p150,95 has a unique alpha chain (CD11c) and shares a beta subunit (CD18) with two other members of the leukocyte adhesion molecule family. The alpha subunit has an extracellular domain containing ten potential glycosylation sites, a transmembrane domain, and a short cytoplasmic tail. It shows homology to alpha subunits of Platelet Glycoprotein IIb/IIIa, Vitronectin Receptor, and Fibronectin Receptor. Receptors involved in cell-cell and cell-matrix interactions belong to a superfamily of integrin genes. (from OMIM 151510 and NCI) (NCI Thesaurus)
Definition 2
Part of the integrin CR4, aka Complement Receptor 4, the CD11c/CD18 heterodimer. (Fundamental Immunology, 3rd ed., William Paul, ed., Raven Press, NY 1993, pg 927) (NCI Thesaurus)
