MeSH definition : An integrin alpha subunit that occurs as alternatively spliced isoforms. The isoforms
are differentially expressed in specific cell types and at specific developmental
stages. Integrin alpha3 combines with INTEGRIN BETA1 to form INTEGRIN ALPHA3BETA1
which is a heterodimer found primarily in epithelial cells.;
