MeSH definition : An integrin alpha subunit that is unique in that it does not contain an I domain,
and its proteolytic cleavage site is near the middle of the extracellular portion
of the polypeptide rather than close to the membrane as in other integrin alpha subunits.; An integrin alpha subunit that is unique in that it does not contain an I-domain,
and its proteolytic cleavage site is near the middle of the extracellular portion
of the polypeptide rather than close to the membrane, as in other integrin alpha subunits.;
