Drosophila integrins and their ligands.

Abstract The major advance during the past year was the identification of ligands for two of the previously known position-specific integrins in Drosophila . At the same time, two new Drosophila integrin subunits (one α and one β) were discovered, and significant progress was made on developmental genetic analyses of integrin functions, shedding light on the roles of integrins in Drosophila development.
