Cloning and characterization of αPS1, a novel Drosophila melanogaster integrin

The Drosophila position-specific integrins (PS integrins or PS antigens) comprise two heterodimeric complexes, α PS1 β PS and α PS2 β PS. With the cloning of α PS1 described here, we complete the characterization of the primary structure of the three PS integrin subunits. We have purified the α PS1...
