MeSH definition : An integrin alpha subunit of approximately 150-kDa molecular weight. It is expressed
at high levels on monocytes and combines with CD18 ANTIGEN to form the cell surface
receptor INTEGRIN ALPHAXBETA2. The subunit contains a conserved I-domain which is
characteristic of several of alpha integrins.;
